TEMPERATURE SENSOR

摘要

A temperature sensor includes a temperature sensitive element, a sheath portion, a surrounding portion, and a holding member. This temperature sensor has a void formed forward of a temperature sensitive body. When the void is projected in an axial direction of the surrounding portion from a forward end side of the surrounding portion, the void contains at least a forward end surface of the temperature sensitive body.
