To provide a sensor device whereby it is possible to prevent a decrease in temperature measurement precision due to interference between a thermocouple wire and a bending piece of a contact plate. A sensor device 1 is provided with a cylindrical casing 10 and a retaining member 51 inserted in the distal end of the casing 10, and is provided with a temperature detection mechanism 40 having a contact plate 41 and thermocouple wires 46, 47 connected to the contact plate 41, the contact plate 41 being retained by the distal end of the retaining member 51, and the contact plate 41 is in contact with a measurement object, whereby the sensor device 1 detects the temperature of the measurement object. The contact plate 41 is formed so as to extend rearward, and has bending pieces 43, 44 retained by the retaining member 51. The retaining member 51 is provided with bending holes 53, 54 in which the bending pieces 43, 44 are inserted and retained and thermocouple wire holes 55, 56 in which the thermocouple wires 46, 47 are inserted, the bending holes 53, 54 and the thermocouple wire holes 55, 56 each being separately formed so as to extend in the axial direction of the casing 10. |
