PROBLEM TO BE SOLVED: To provide a solid state relay which requires no separate wiring of CT (current transformer) and can reduce its wiring manhour. SOLUTION: A terminal part 21 of an element module 20 containing a triac that functions as an output element and a connecting shaft 12 as a conductor member piercing through an attachment hole of a terminal part 25 of a printed circuit board 16 are attached together by means of a nut 27. A barrel part 28a of an insulated CT holder 28 holding a CT 19 is fitted to the shaft 12. Thus, the shaft 12 pierces through a hollow part of a toroidal coil of the CT 19 and is built into a easing and the upper end of the shaft 12 serves as an output terminal of this solid state relay.
