A power on/off control circuit and an electronic device is provided, the circuit including: a switching element, a first semiconductor switching circuit including a first semiconductor switching element, a second semiconductor switching circuit including a second semiconductor switching element, and a holding circuit connected between a first terminal of the first semiconductor switching element and a second terminal of the second semiconductor switching element. When the switching element is closed, the first semiconductor switching element is turned on. When the first semiconductor switching element is turned on, the second semiconductor switching element is turned on, and a power on signal is output via the second terminal of the second semiconductor switching element. When the second semiconductor switching element is turned on, the holding circuit is operable to maintain the on state of the first semiconductor switching element. The control circuit can stably lock a started state.
