PROBLEM TO BE SOLVED: To provide a wound type electrochemical device having excellent reliability.SOLUTION: In an electrochemical device, a pair of opposing electrodes is wound via a separator and a wound body A is housed in a container constituted of an enclosure F and a pair of terminal boards B and C. In the electrode, on a strip-like metal foil, an active material layer is formed excluding the end of the strip-like metal foil in the width direction, and at the end, a resin layer X is provided including a conductive filler. Furthermore, the metal foil and the resin layer including the conductive filler are joined to a neighboring terminal board when being housed in the container. |
