Coin-shaped cell

A coin-shaped cell, comprising:

• 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;
• and
• a 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, and wherein 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.
