Abstract
A protective circuit includes a first capacitance element and a second capacitance element. A first capacitance value of the first capacitance element increases with an increase in a voltage applied to a first terminal of a circuit element. The second capacitance element is connected in series with the first capacitance element between the first terminal and a second terminal which is a reference potential terminal. The second capacitance element has a second fixed capacitance value which is larger than the first capacitance value until the voltage reaches a first value. The second capacitance element has a breakdown voltage characteristic higher than a breakdown voltage characteristic of the circuit element.
