Abstract
An optical fiber temperature sensor includes: a substrate having a first substrate main body, and a second substrate main body, which has a coefficient of thermal expansion larger than that of the first substrate main body, and is bonded to the first substrate main body; and an optical fiber having a FBG sensor portion for measuring a temperature from a relationship between a Bragg wavelength and the temperature, and the optical fiber is configured to be embedded in the second substrate main body so that the FBG sensor portion is positioned in the second substrate main body.
