A pilot on-off valve in a refrigeration cycle device includes a main on-off valve that opens or closes a bypass passage through which a high-pressure side portion and a low-pressure side portion of a cycle communicate with each other, and a pilot valve that opens or closes a communication passage through which an inflow port and an outflow port of the pilot on-off valve communicate with each other. When the main on-off valve opens the bypass passage, the pilot valve opens the communication passage in a state where a refrigerant passage, in which a refrigerant flowing out of the pilot on-off valve flows, is closed.
