BATTERY

摘要

Disclosed is a battery having improved life. Specifically disclosed is a battery which comprises: an electric power generating element (21) in which one or more unit cell layers each constituted by sequentially laminating a positive electrode, an electrolyte and a negative electrode are laminated; a first collector plate (25) which is provided on the outermost positive electrode surface of the electric power generating element (21); a second collector plate (27) which is provided on the outermost negative electrode surface of the electric power generating element (21); a conductive projected part (41) or (42) which is provided on either the first collector plate (25) and/or the second collector plate (27) and has a width that is not less than a half of the width of the ends of the collector plate (25) or (27); and a terminal (44) or (45) which is fitted to the projected part (41) or (42) and takes out an electric current from the projected part (41) or (42).
