<P>PROBLEM TO BE SOLVED: To provide a solid battery and a method of manufacturing the same, capable of reducing internal resistance. <P>SOLUTION: The solid battery includes an axis center member, a cylindrical electrode body arranged around the axis center member, and a case housing the axis center member and the electrode body. The electrode body includes a cathode, an anode, and a solid electrolyte layer arranged between the cathode and the anode. As a component of the axis center member, a material with a larger coefficient of thermal expansion than that of the case is contained. The manufacturing method of the solid battery which contains a material with a larger coefficient of thermal expansion than that of the case for a component of the axis center member, includes a process for manufacturing a structure body equipped with the axis center member and the cylindrical electrode by forming the cylindrical electrode body having a cathode, an anode and a solid electrolyte layer arranged between the cathode and the anode around the axis center member with its temperature retained lower than the normal temperature, a process for housing the manufactured structure body into the case while retaining the axis center member as a lower temperature than the normal temperature, and restraining circumference of the structure body, and a process for raising the temperature of the axis center member more than the normal temperature after the former process. <P>COPYRIGHT: (C)2011,JPO&INPIT |
