PURPOSE:To obtain an easily produced and high-performance thermoelectric element in which fine thermoelectric element pieces are formed much in several thousands, by pressing/molding thermoelectric material powder on a substrate on which a material not reacting to a thermoelectric material during sintering is formed thinly, and by coating the thermoelectric material reinforcedly with organic resin after the sintering and next removing the substrate by an etching method or the like. CONSTITUTION:A thermoelectric material powder is pressed/molded on a substrate 3 on which a material 2 not reacting to a thermoelectric material during sintering is formed thinly, and after the sintering the thermoelectric material 1 is coated reinforcedly with organic resin 5. In succession, the substrate 3 is removed by an etching method or the like, and a composite member which is thus formed of the thermoelectric material 1 and the organic resin 5 is used to manufacture a thermoelectric element. For example, powder of a (Bi,Sb)2 (Se,Te)3 group is used as the thermoelectric material 1, and a glass layer or the like is formed as a reaction preventing layer 2 by a sputtering method. A copper plate is used as the substrate 3. The composite members, each of which is formed unitedly of the organic resin 5 and the thermoelectric material 1 as aforementioned, are laminated and arranged regularly in quantity with the thermoelectric materials 1 being buried in the organic resin 5, so that electrodes 6 of N and P types connected in series are formed. |
