[0057] Such as figure 1 and figure 2 As shown, a temperature sensor device 2 according to one embodiment of the present invention has a thermosensitive element 4 . The thermosensitive element 4 has an element body 6 and a coating layer 7 covering the outer periphery of the element body 6 .
[0058] The element body 6 is not particularly limited as long as it can detect temperature, and for example, an NTC (Negative Temperature Coefficient) thermistor element, a PTC (Positive Temperature Coefficient, Positive Temperature Coefficient) thermistor element, etc. can be used. The cover layer 7 can be made of insulating resin, glass, or the like. The resin constituting the coating layer 7 is not particularly limited, and for example, epoxy resin, urethane resin, silicone resin, ABS resin, PPS resin, PBT resin, etc. can be used. In addition, the glass constituting the cladding layer 7 is not particularly limited.

[0079] Such as Figure 6 As shown, the temperature sensor device 2a of the present embodiment is different from the first embodiment only in the structure in which the metal fitting 10a is attached, and is the same as the temperature sensor device 2 of the first embodiment except for the structure and effects shown below, and in Common parts are denoted by common symbols, and illustrations and descriptions of common parts are omitted.
[0080] Such as Figure 6 As shown, in this embodiment, the mounting bracket 10 a has a cylindrical portion 17 formed by integrally connecting upper ends of a pair of side walls 14 with an upper wall 15 so as to cover the four sides around the thermosensitive element 4 . An inner convex portion 20 is formed on the inner surface of the cylindrical portion 17 . In this embodiment, the inner convex portion is not only on the inner surface 14d of the side wall 14 but also on the inner surface 12d of the bottom wall 12 and the inner surface 15d of ...

[0083] Such as Figure 7 As shown, the temperature sensor device 2b of this embodiment differs from the first embodiment only in the inclination angle θ of the thermal sensor 4 and the lead wire 8 relative to the mounting metal part 10, and is different from the first embodiment except for the structure and effects shown below. The embodiment and the second embodiment are the same, and the common parts are given the same symbols, and the illustration and description of the common parts are omitted.
[0084] Such as Figure 7 As shown, in this embodiment, the thermosensitive element 4 and the lead wire 8 are inclined at an inclination angle θ of about 0 to 30 degrees with respect to the plane of the bottom plate 12 of the mounting metal fitting 10 . In this state, the front end portion of the heat sensitive element 4 is mounted on the mount through the adhesive resin 30 present in the space surrounded by the bottom wall 12 and the pair of side walls 14 of the mount metal fitti...
