COIN-SHAPED CELL

A coin-shaped cell, containing:a battery cell case having a bottom plate and a side portion rising from a rim of the bottom plate;a sealing plate having a top plate and a rim portion extending from the top plate to the inside of the side portion;a gasket compressed and interposed between the side portion and the rim portion;power generation elements sealed by the battery cell case, the sealing plate, and the gasket; anda pressure-sensitive conductive film disposed on an outer surface of at least one of the battery cell case and the sealing plate;wherein the pressure-sensitive conductive film includes a first elastomer layer that holds conductive particles, and a second elastomer layer which is disposed on at least one surface of the first elastomer layer and is in contact with at least a part of the conductive particles among the conductive particles held to the first elastomer layer, andwherein an average particle diameter of the conductive particles is equal to or larger than a thickness of an elastomer part of the first elastomer layer, and the conductive particles are disposed in a single layer in a planar direction of the first elastomer layer.
