Kind Code:
A1
Abstract:
The present invention provides an electrochemical element which is capable of maintaining good electrical connection, and in which a conductive plate that is to be arranged between a power generation element and a cover member can be easily fitted. An electrochemical element 1 according to the present invention is provided with: a case 10 which comprises a recessed container 11 that has a bottom part 111 and a lateral wall part 112, and a cover member 12 that covers the opening of the recessed container 11; a power generation element 20 which comprises a multilayer body that is obtained by stacking an electrode layer 21, an electrode layer 22 and a solid electrolyte layer 23, and which is contained in the internal space of the case 11 in such a manner that the bottom part 111 and the electrode layer 21 face each other; and a conductive plate 30 which is arranged between the electrode layer 22 and the cover member 12 at the opening side of the recessed container 11. The recessed container 11 has a plurality of insertion holes 115 which have openings in the upper end surface of the lateral wall part 112. The conductive plate 30 has, on the peripheral edge thereof, a plurality of elastic lock parts 31 at positions corresponding to the plurality of insertion holes 115. In a state where the elastic lock parts 31 are respectively inserted into the insertion holes 115, the front end parts 311 of the elastic lock parts 31 press the lateral surfaces of the insertion holes 115.
