<p>The present invention reduces components of a circuit board and miniaturizes a battery pack using a thermostat. The battery pack includes a thermostat (9) having a casing portion (10) formed of a nonconductive material, a first electrode portion (13) disposed at one surface (10a) of the casing portion, and a second electrode portion (18) and (18) disposed at another surface (10c) opposite to the one surface of the casing portion, wherein one electrode lead (5) projected from a battery cell (3) is connected to one electrode connecting portion (7) of a circuit board (4); another electrode lead (6) is connected to the first electrode portion of the thermostat; and the second electrode portion of the thermostat is connected to another electrode connecting portion (8) of the circuit board. <IMAGE></p> |
