<P>PROBLEM TO BE SOLVED: To provide a battery pack which has a substrate holder and a circuit board on an end surface of a rectangular type unit cell, which has a cap to cover the circuit board and the substrate holder, and which has improved strength against bending with a simple configuration. <P>SOLUTION: A bottom plate part 21 of a substrate holder 20 is closely attached along the surface of a sealing lid 12. A periphery of a circuit board 30 derived from near the center of the bottom plate part 21 is supported by these side plate parts 22a to 22e. The substrate holder 20 has a pair of ribs 23a and 23b extended from the bottom plate part 21 downward to clip the upper end portions of the principal surfaces 10a and 10b of a unit cell 10. The skirt portions 42a and 42b of a cap 40 are engaged to the outside of the side plate parts 22a and 22b of the substrate holder 20, which allows for the cap 40 to be fit and fixed to the substrate holder 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
