description The objective of the present disclosure is to provide a cylindrical battery in which it is possible to fix an insulating plate disposed in an upper portion between an electrode body and a sealing plate. A cylindrical battery (10) is provided with: an electrode body (14) in which a positive electrode (11) and a negative electrode (12) are wound with a separator (13) interposed therebetween; an electrolyte; a bottomed cylindrical outer can (20) accommodating the electrode body (14) and the electrolyte; a sealing plate (30) blocking an opening portion (20A) of the outer can (20); a gasket (31) disposed on a peripheral edge portion of the sealing plate (30); and an upper insulating plate (15) disposed between the electrode body (14) and the sealing plate (31). The gasket (31) is compressed in the radial direction between an edge surface of the peripheral edge portion of the sealing plate (30) and the outer can (20), and the outer can (20) includes a locking portion (20D) with which a peripheral edge portion (15B) of the upper insulating plate (15) engages.
