<p><P>PROBLEM TO BE SOLVED: To provide an electrochemical device capable of avoiding an increase in connection resistance (conduction resistance) between the top face of a power collection film and the face of one electrode side of a power storage element. <P>SOLUTION: In an electrochemical device 10, the bottom face 11a1 of the first recess 11a of a case 11 has an opening outline that is smaller than the outline of the undersurface of the first electrode sheet 13a of a power storage element 13, and a second recess 11b having a predetermined depth D11b is formed on the bottom face 11a1. A power collection film 19 has a thickness T19 which is smaller than the depth of the second recess 11b and provided on the bottom face 11b1 of the second recess 11b. An adhesive material reservoir AR having a depth corresponding to a dimension (=D11b-T19) obtained by subtracting the thickness T19 of the power collection film 19 from the depth D11b of the second recess 11b is formed between the bottom face 11a1 of the first recess 11a and the top face of the power collection film 19. A first conductive adhesive layer 20 is provided so as to be filled in the adhesive material reservoir AR. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
