Sensor device is provided with body, formed at the interior of which is gas passage into which steam serving as detection target flows; and pressure sensor, which is installed at body so as to be in communication with gas passage and which detects pressure of steam within gas passage. Body has rod-shaped portion having cylindrical inside circumferential surface. Sensor device is provided with sheath pipe (insert) that is formed in the shape of a rod on which helical groove is formed at outside circumferential surface, and that is such that, when inserted within rod-shaped portion of body, helical groove, together with inside circumferential surface of rod-shaped portion, form helically shaped gas passage (helical passage).
