形電池。 The positive electrode side consists of a flat cylindrical positive electrode can with a bottom, a disk-shaped positive electrode mixture crimped to the inner bottom surface of the positive electrode can, and a separator containing an electrolyte placed on the top surface of this positive electrode mixture. For the assembled product, there is a negative electrode side assembly consisting of a dish-shaped negative electrode terminal plate, a disc-shaped negative electrode crimped to the inner surface of the negative electrode terminal plate, and an annular sealing gasket fitted and attached to the periphery of the negative electrode terminal plate. In a flat battery having a structure in which the product is fitted into the inner peripheral part of the positive electrode can and the opening edge of the positive electrode can is curled inward to compress the sealing gasket and seal the inside of the battery. . A flat battery, characterized in that a vertical groove for venting air is formed along the axial direction on the inner surface of the inner cylinder of the sealing gasket.
