摘要： A coin-shaped cell containing a battery cell case having a bottom plate and side portion; a sealing plate; a gasket compressed and interposed between the side and a rim portion; power generation elements sealed by the case, the sealing plate, and the gasket; and a pressure-sensitive conductive film disposed on an outer surface of one of the case and the sealing plate. 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. 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.
