1. A temperature detection device, comprising:
a temperature sensor including a thermosensitive body configured to detect temperature of a coil of a rotary electric machine to be mounted on a vehicle; and
a metal bracket configured to attach the temperature sensor to the coil, wherein:
the bracket includes a bracket main body configured to clamp the coil by elastic force, and a joining portion joined to the temperature sensor,
the bracket main body includes a clamping portion configured to internally clamp the coil, and a heat collection portion that protrudes to outside of the clamping portion and is thermally coupled to the temperature sensor, and
the temperature sensor is disposed between a wall of the clamping portion and a facing portion of the heat collection portion facing the wall.
