1. A temperature sensor detecting a temperature of a coil provided in a stator of a rotary electric machine, the temperature sensor comprising:
a sensor element including a thermosensitive body, electric wires electrically connected to the thermosensitive body, and an elongated covering body enclosing a part of the electric wires and the thermosensitive body, and configured to be inserted into a gap formed by the coil along a longitudinal direction of the covering body; and
a bracket including a fixed portion to be fixed to the stator, and a supporting portion pressing one end of the sensor element in the longitudinal direction against the coil by an elastic force of the supporting portion while supporting the covering body.
