PROBLEM TO BE SOLVED: To provide temperature sensors with even characteristics manufactured at inexpensive cost.SOLUTION: A temperature sensor according to the present invention comprises: a sensing member 10; a holding member 30 that fixes and holds the sensing member; an optical fiber that illuminates the sensing member with light and guides light reflected by the sensing member; and a sleeve 90 that is cylindrical and houses the optical fiber. The holding member is tabular and has a notch provided in at least one of a peripheral part of a non-holding surface 30b that is at a side opposite to the surface on which the sensing member is fixed and held and a side surface thereof. The holding member is fixed on an end of the sleeve in such a manner that the non-holding surface is exposed outwardly. The end of the sleeve engages with the notch. |
