A temperature detection module includes: a temperature sensor; a sensor holder for holding the temperature sensor such that movement is possible in a separation and contact direction in which the temperature sensor is separated from and brought into contact with a measurement target; and a biasing member that is attached to the sensor holder and biases the temperature sensor such that a detection surface comes into contact with a measurement target. The sensor holder includes: a base portion; and an accommodating portion that extends in the separation and contact direction from the base portion and holds the temperature sensor such that movement is possible in the separation and contact direction. The accommodating portion includes a gap that allows inclination of the temperature sensor between the accommodating portion and the temperature sensor.
