Manufacturing method of thermoelectric converter

摘要

An insulating substrate to which intermediate portions or conductive pastes constituting the intermediate portions are disposed, a front surface protective member to which front surface patterns are formed, and a back surface protective member to which back surface patterns are formed are prepared. A laminated body, to which first end portions or conductive pastes constituting the first end portions are disposed between the intermediate portions or the conductive pastes constituting the intermediate portions and the front surface patterns, and second end portions or conductive pastes constituting the second end portions are disposed between the intermediate portions or the conductive pastes constituting the intermediate portions and the back surface patterns, is constituted. Then, thermoelectric conversion elements are formed by integrating the laminated body.

1. A method for manufacturing a thermoelectric converter that has an insulated substrate to which a plurality of thermoelectric conversion elements are disposed;
a surface protecting member disposed on a front surface of the insulating substrate and formed with front surface patterns that are electrically connected to predetermined thermoelectric conversion elements; and a back protective member disposed on a back surface opposite to the front surface of the insulating substrate and formed with back surface patterns that are electrically connected to the predetermined thermoelectric conversion elements; wherein, each of the thermoelectric conversion elements has a first end portion connected to the front surface pattern, a second end portion connected to the back surface pattern, and an intermediate portion that connects the first end portion and the second end portion; and the thermoelectric conversion element of which sectional areas of the first and the second end portions in a direction parallel to a plane direction of the insulating substrate are configured to be larger than sectional areas of intermediate portions, the method comprising: a process of preparing the insulating substrate to which a plurality of via holes penetrating through in a thickness direction are formed, and the intermediate portion or a conductive paste constituting the intermediate portion is disposed in the via holes; a process of preparing the front surface protective member to which the front surface patterns are formed; a process of preparing the back surface protective member to which the back surface patterns are formed; a process of constituting a laminated body by disposing the front surface protecting member on the front surface of the insulating substrate and disposing the back surface protective member on the back surface of the insulating substrate; and a process of integrating the laminated body; wherein, the first end portion or a conductive paste constituting the first end portion is disposed between the intermediate portion or the conductive paste constituting the intermediate portion and the front surface pattern, and the second end portion or a conductive paste constituting the second end portion is disposed between the intermediate portion or the conductive paste constituting the intermediate portion and the back surface pattern to constitute the laminated body in the process of constituting the laminated body; and the thermoelectric conversion element having the first and the second end portion and the intermediate portion is formed by applying pressure in a laminating direction while heating to the laminated body in the process of integrating the laminated body.
