1. A temperature sensor comprising:
a sensor element including a heat-sensitive body configured to contact with a detection object, a pair of lead wires connected with the heat-sensitive body, and connecting wires connected with the lead wires respectively; and
a holding element including a fixed body configured such that a position of the fixed body is fixed to an object appliance, and a movable body configured to support the heat-sensitive body of the sensor element and to reciprocate between a first position and a second position relative to the fixed body, wherein
each of the lead wires includes a first core wire formed of a solid wire,
each of the connecting wires includes a second core wire formed of a twisted wire and a second insulating covering that covers the second core wire,
a conducting wire constituting the twisted wire has a smaller wire diameter than the solid wire,
the second core wire of each of the connecting wires includes a deformable region having a strength lower than that of the first core wire of each of the lead wires,
each of the lead wires and each of the connecting wires are connected through a connection portion between a first exposed part where the first core wire is bared and a second exposed part where the second core wire is bared, and
the deformable region is included in the second exposed part.
