。 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 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. A structure in which the assembly is fitted to the inner bottom surface of the inner peripheral surface of the positive electrode can, and the opening edge portion of the positive electrode can is curled inward to compress the sealing gasket and seal the inside of the battery. 1. A flat battery, characterized in that a notch groove for air venting is formed in the peripheral edge of the upper surface of the positive electrode mixture.
