PROBLEM TO BE SOLVED: To provide a temperature sensor capable of being precisely attached to an attachment part even while permitting unevenness of thickness of attachment parts such as an air duct or the like, and to provide a battery pack having the temperature sensor.SOLUTION: A temperature sensor 50 measures temperature by a thermistor 55 provided at a shank part 51 to be inserted into a through-hole 42 from a tip part 53. The shank part 51 includes: an umbrella part 52 extended in a direction being separated from the shank part 51, between a base end part 54 and the tip part 53, and being in contact with an outer edge part of the through-hole 42; and an elastic extension part 60 diverging from the tip part 53, and extended in a direction of the umbrella part 52 with elasticity given in a direction orthogonal to the shank part 51. The elastic extension part 60 has, at an extended end part, a latch part 60C separated from the umbrella part 52, for latching insertion of the shank part 51 into the through-hole 42. The latch part 60C has, on a reverse face of a surface facing the shank part 51, a contact surface 63 inclined in a direction of reducing a diameter from the tip part 53 to the base end part 54 of the shank part 51, and being in contact with a periphery of the through-hole 42. |
