出装置。[Claims for Utility Model Registration] 1. A permanent magnet 4 inside the heat sensitive element 1, which has a temperature sensitive element 3 attached therein and advances or retreats depending on the presence or absence of a heated object to control the energization of the hot plate 12. In a temperature sensor equipped with a reed switch 8 whose contacts are switched by changes in magnetic flux, the direction of advance and retreat of the heat sensitive element 1 is parallel to the longitudinal direction of the reed switch 8, and the position of the contact is set to the center plane of the magnetic pole. A heat detection device placed on top. 2. The heat detection device according to claim 1, wherein the reed switch 8 is disposed in a ring-shaped center hole whose thickness direction is the direction of magnetization of the permanent magnet 4. 3. A shielding tube made of a magnetic material, which is inscribed in the center hole of the ring-shaped permanent magnet 4 and circumscribed to a part of the reed switch 8, is installed inside the bottom of the outer case 7 that supports the forward and backward movement of the heat sensitive element 1. A heat detection device according to claims 1 and 2 of the utility model registration claim, which is installed vertically.
