摘要：
A protection circuit 2 of a first embodiment comprises a resistance-variable switch 10, an overcurrent detection unit 20, a control voltage application unit 30, a capacity unit 40, a control terminal voltage change unit 50, and an outer terminal 11. The resistance-variable switch 10 has a control terminal 10a, a first terminal 10b, and a second terminal 10c. The control terminal voltage change unit 50 includes a switch 51 and a resistor 52 which are provided in series between the control terminal 10a of the resistance-variable switch 10 and a reference potential terminal.
