ABSTRACT:
A temperature sensor which contacts with a curved-surface body to be measured to sense a temperature thereof is provided with a support member having a bow-shaped surface; a thin film strung and laid between both ends in a direction of curvature (e.g., bow-shaped direction) of the bow-shaped surface; and a heat sensitive element disposed at a portion of the thin film. The portion being opposed to the bow-shaped surface. Also, the space portion side of the heat sensitive element may be coated with aluminum foil and a protect plate formed of aluminum, phosphorous bronze or copper is disposed on the body to be measured side of the heat sensitive element. Further, the temperature sensor may be incorporated in an apparatus that fixes the temperature sensors to the bow-shaped surface.
