Temperature detection device and assembly thereof

A metal bracket for attaching a temperature sensor to a coil of a rotary electric machine to be mounted on a vehicle, the temperature sensor including a thermosensitive body configured to detect temperature of the coil, the metal bracket comprising:

• a bracket main body including 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 couplable to the temperature sensor, and
• a joining portion joined to the temperature sensor,
• wherein the clamping portion is a U-shaped body that opens in a direction toward the heat collection portion, and
• wherein the joining portion is joined to a joined portion of the temperature sensor that is located at a position different from the thermosensitive body.
