CYLINDRICAL BATTERY

The present invention provides a cylindrical battery in which the opening end of an outer can has an external terminal of a different polarity from a sealing body and easily connectable to an external lead. A cylindrical battery (10) that is one embodiment described in the present disclosure comprises: an electrode body (14) that includes a positive electrode (11) and a negative electrode (12); a bottomed cylindrical outer can (16) that houses the electrode body (14) and is connected to one of the positive electrode (11) and the negative electrode (12); and a sealing body (17) that is connected to the other of the positive electrode (11) and the negative electrode (12). The outer can (16) has a groove (23), and an opening end (16a) that extends radially outward. The sealing body (17) is fixed by crimping between the groove (23) and a pressing member (24) with a gasket (18) interposed therebetween, said pressing member (24) being joined to the opening end (16a).
