A square secondary battery includes a generating element having an electrode; a battery can holding the generating element; a battery lid that seals an opening of the battery can; an external terminal arranged on the battery lid; and a current collector connecting the electrode of the generating element to the external terminal. The external terminal has a bus bar joint to which a bus bar is connected and a current collector joint to which the current collector is connected, the bus bar joint and the current collector joint being integrally juxtaposed on the battery lid. The current collector joint has a cylindrical insertion part to be inserted into a through hole in the battery lid and also has a sealing part arranged at an outer periphery of the insertion part, the sealing part pressing down a sealing member.
