Abstract

The laminated battery disclosed herein includes an electrode body, an outer casing made of a laminated film which accommodates the electrode body, and an electrode terminal. The outer casing has a weld portion in which inner surfaces of the laminated films are stacked and welded together in a peripheral edge of space which accommodates the electrode body. The electrode terminal passes between the laminated films stacked on each other in the weld portion and is inserted into the outer casing, one end of the electrode terminal is electrically connected to the electrode body, and another end of the electrode terminal is exposed to outside of the outer casing. In addition, at least a part of the electrode terminal inserted into the outer casing is plate-shaped. In the plate-shaped portion, a surface-roughened portion having a notch portion is provided at a position of the weld portion.
