description The purpose of the present disclosure is to provide a cylindrical battery in which a shoulder part extends radially inward of a sealing body from an inner end of a groove part while suppressing deformation of the groove part. The cylindrical battery according to an exemplary embodiment comprises: a bottomed cylindrical outer can including a bottom surface part and a side surface part; a sealing body that closes an opening part of the outer can; and a gasket disposed between the outer can and the sealing body. The outer can has: a groove part that is formed such that a side surface section thereof extends from the outside to the inside and supports the sealing body with the gasket therebetween; and a shoulder part that is formed to face the groove part with the sealing body and the gasket therebetween and sandwiches the sealing body together with the groove part. At least a portion of the shoulder part extends radially inward of the sealing body from an inner end of the groove part, and an easily deformable part is formed on the shoulder part along the circumferential direction of the outer can.
