<P>PROBLEM TO BE SOLVED: To provide a power supply device that can minimize increases in the number of components and work man-hour requirements and can keep the device compact, light and inexpensive even with increasing battery cells. <P>SOLUTION: The power supply device comprises: a battery assembly 1 having a plurality of stacked battery cells 2, 3, and having electrodes 2b, 3b of adjacent battery cells 2, 3 opposed to each other; and a battery coupling block 10 arranged on the side of the battery assembly 1 where the electrodes 2b, 3b project to cover the projecting electrodes 2b, 3b. The battery coupling block 10 has a substrate 12 having a circuit pattern section 17 for voltage detection, and the opposed electrodes 2b, 3b are directly connected to the circuit pattern section 17. <P>COPYRIGHT: (C)2013,JPO&INPIT |
