The present invention aims to provide a sealed battery having superior performance due to favorable welding of a terminal of a seal cover and a current collector body provided below the seal cover, and a manufacturing method for the sealed battery. In the sealed battery, one of a positive-electrode plate and a negative-electrode plate is electrically connected, via a current collector body, to a terminal of a seal cover which seals an outer can. The current collector body is a single-piece plate member that has a main body and a tab extending from the main body. The tab passes through an insulating ring and bends back such that part of the insulating ring lies between a tip of the tab and the main body of the current collector body. The main body is resistance welded to the electrode assembly, and the bent back tab is resistance welded to the terminal.
