Abstract

[PROBLEMS] To provide a solid state relay which can suppress cost increase, prevent abnormal operation, and prevent failure of resistor-associated parts of a snubber circuit. [MEANS FOR SOLVING PROBLEMS] A solid state relay (20) includes a third connection line (28c) which connects a connection point d between a capacitor C0 and a resistor R0 constituting a snubber circuit S to a gate terminal G of a triack TA. Furthermore, the solid state relay (20) includes: a resistor R2 arranged on the third connection line 28c; and a capacitor C arranged between a connection point e and a connection point b.
