Title: ELECTROCHEMICAL DEVICE, AND PRODUCTION METHOD
Abstract:
[Problem] To provide an electrochemical device and a production method, with which peeling between an electrode adhesive layer and a case can be suppressed. [Solution] This electrochemical device (100) is provided with: a case (10); an electrical storage element (13); and an adhesive layer (19). The case (10) is provided with: terminal parts (14); a case main body (11) provided with a first inner surface (11a) having the terminal parts (14) provided thereto; and a conductive lid (12) which is bonded to the case main body (11), and which is provided with a second inner surface (12a) that faces the first inner surface (11a). The electrical storage element (13) is provided with: a first electrode (13a) which is fixed to the first inner surface (11a); and a second electrode (13b) which is fixed to the second inner surface (12a), and which faces the first electrode (13a) with an electrolyte solution provided therebetween. The adhesive layer (19) is configured from a cured product of a conductive adhesive material, said cured product being provided with at least one cavity portion (19c). Furthermore, the adhesive layer (19) electrically connects the first electrode (13a) and the terminal parts (14), and is disposed between the first electrode (13a) and the first inner surface (11a).
