Temperature sensor

A temperature sensor comprising:

• a temperature measurement unit that is configured to measure a temperature of a measurement object, the temperature measurement unit having a heat-sensitive body and a pair of electric wires electrically connected to the heat-sensitive body;
• a holding portion that holds the temperature measurement unit and is composed of a single member;
• and
• an elastic portion that applies an elastic force to the temperature measurement unit toward the measurement object, the elastic portion being provided between the temperature measurement unit and the holding portion, wherein
• the electric wires of the temperature measurement unit are pulled out from the holding portion along a first direction in which the elastic force is applied, wherein
• the holding portion includes an accommodation portion that accommodates the elastic portion and opens in a second direction that intersects the first direction in which the elastic force is applied, wherein
• the elastic portion is composed of a compression coil spring, and wherein
• the electric wires are pulled out from the holding portion through a central empty space of the compression coil spring.
