<P>PROBLEM TO BE SOLVED: To provide a battery pack having high energy efficiency while restraining manufacturing costs from increasing. <P>SOLUTION: A flat plate-like clad plate 101 is jointed to one region of a principal plane of a hole sealing plate 10a. One element lead plate of a PTC element 21 extends outward in a Y-axis direction from an element body. A tip portion of one element lead plate is jointed to the clad plate 101. When the PTC element 21 and a circuit board 22 are seen from outside in an X-axis direction, a jointing portion of the element lead plate of the PTC element 21 of the clad plate 101 is arranged at a position out of a board body 220, and the element lead plate of the PTC element 21 and the hole sealing plate 10a are jointed to each other while the clad plate 101 is nipped in its thickness direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
