A plurality of battery modules formed by connecting a plurality of unit cells in series in electrical and mechanical series are arranged in parallel to be held in a holder case, and electrically connected between terminals of the battery module to respective hard plates located at both ends of the holder case. In the battery power supply which installed a pass bar,
The hard plate is composed of a resin plate, the pass bar is fixed to the hard plate by insert molding,
A lead wire for measuring the voltage between the terminals of one or more battery modules is embedded in the hard plate by insert molding,
A fuse is disposed in the middle of a lead wire for measuring the voltage between the terminals, and the fuse is installed on a fuse attachment piece fixed by insert molding on a hard plate.
