1. A temperature sensor used with being attached to an electric motor, to detect a temperature of a coil wound around a core of the electric motor, the temperature sensor comprising:
a sensor element including a thermosensitive body, paired electric wires electrically connected to the thermosensitive body, and an electrically insulating covering body covering the thermosensitive body and the paired electric wires; and
a housing including an abutting housing portion abutting on the coil, and a supporting housing portion extending in a direction intersecting with the abutting housing portion and supported by the core, the housing holding the sensor element, wherein
the electrically insulating covering body protrudes from the abutting housing portion at a position separated by a predetermined distance from the supporting housing portion.
