The disclosed circuit breaker comprises a first connection terminal, a second connection terminal, a heat generating part having conductivity and disposed between the first connection terminal and second connection terminal, an igniting part igniting depending on a cut-off signal, an expandable elastic member capable of applying a force to the heat generating part so as to be departed from between the first connection terminal and second connection terminal, a container accommodating the heat generating part, igniting part and elastic member, and a retaining part for retaining the elastic member in compressed state. Herein, at least a portion of the retaining part is provided in the container, and as the igniting part ignites depending on the cut-off signal and the heat generating part generates heat, and the retaining part releases the elastic member, the elastic member applies the force to the heat generating part, and the heat generating part is departed from between the first connection terminal and second connection terminal, so that the conductive state between the first connection terminal and second connection terminal is cut off.
