BUS BAR

A bus bar (1) includes members (9) made from a conductive material and consecutively arranged to form a plate shape defining a wiring pathway (7). The members (9) adjacent to each other are connected to each other by laser joining. The members (9) include a first connection member (11) arranged at one end of the wiring pathway (7) and having a first connection portion (17) for electrical input-output, and a conductive member (13) connected to the first connection member (11) in a state where connection surfaces (23, 25) of the first connection member (11) and the conductive member (13) located in a same plane are in contact with each other. In the members (9), only the first connection member (11) is plated.
