Abstract
A current sensor detects a current flowing through a first buss bar . When a current value detected by the current sensor became equal to or greater than a threshold current value, a CPU outputs a driving control signal to a driving circuit and the driving circuit operates an, ignitor through a second substrate and a terminal Therefore, the ignitor ignites, a second projection is melted by heat of a heating agent a compression spring is expanded and a thermite case jumps up. Thus, electrical connection between the thermite case and the first and second buss bars is interrupted. Further, since an outer container in which the current sensor the CPU and the driving circuit are accommodated is integrally assembled with the cap and the resin case in which the thermite case the ignitor the compression spring and the second projection are accommodated, non-operational state of the ignitor due to disconnection of electric wire is not generated.
