Provided is a safety valve (20) that comprises: a housing (21) that has a low-pressure chamber (31) that communicates with the outside and a high-pressure port (32) that opens into the low-pressure chamber; a valve body (22) that integrally forms a shaft part (41) which is inserted from the low-pressure-chamber side into the high-pressure port, and a large-diameter part (42) which is arranged in the low-pressure chamber, the valve body being movable in an axial direction of the shaft part with respect to the housing; an urging member (23) that urges the valve body toward a front side in the insertion direction of the shaft part; and an annular seal member (24) that is provided around an inner periphery of the high-pressure port and fills a space between an outer periphery of the shaft part and the inner periphery of the high-pressure port. In the shaft part, formed are valve body communication paths (43) that communicate with the high-pressure port by each having an opening which opens at a portion of the outer circumference of the shaft part in a circumferential direction, and by also being open at an end of the shaft part in the axial direction.
