PROBLEM TO BE SOLVED: To provide a power supply device capable of blocking a current supply path with certainty in the case that expansion of a battery is generated, by a simple and low-costed configuration with a small number of components.SOLUTION: In a power supply device 2, a conductive connection member 31 connecting battery terminals 16 of upper and lower nonaqueous secondary batteries 1 is arranged in such a state that the member receives a tension force by deformation caused by raise in an internal pressure of the nonaqueous secondary batteries 1, and has a first member 32 and a second member 33 separable by receiving the tension force. |
