PROBLEM TO BE SOLVED: To provide an electrochemical device in which insulation quality inspection can be carried out accurately and simply.SOLUTION: An electrochemical device (1) is housed while sealing the device body (30) in an exterior body (20). Tab leads (31), (32) are bonded, respectively, to the positive electrode and negative electrode of the device body (30), the exterior body (20) is formed by arranging the heat-sealable resin layers of a laminate exterior material, where the heat-sealable resin layer is bonded the first surface of a metal foil layer and the heat-sealable resin layer is boded to the second surface, inward. A conduction terminal (7), from which the heat-resistant resin layer is removed, is provided on a part of the outer surface of the exterior body (20), and at the edge of the exterior body (20), the heat-sealable resin layers of the laminate exterior material are fused, while leading out the ends of the tab leads (31), (32) from the exterior body (20).SELECTED DRAWING: Figure 1A |
