Abstract
A temperature measurement sensor according to an exemplary embodiment includes a substrate and an optical fiber provided on an upper surface of the substrate and extending along the upper surface. The temperature measurement sensor further includes a light introduction path of a space that allows a space above the upper surface and a space below a lower surface of the substrate to communicate with each other and an optical coupling portion provided on the upper surface and disposed in the light introduction path. The optical coupling portion is optically connected to the end surface of the optical fiber. The optical fiber forms the first pattern shape and the second pattern shape. The first pattern shape includes the optical fiber more densely than the second pattern shape. Light incident on the optical coupling portion from a side of the lower surface through the light introduction path reaches the end surface through the optical coupling portion.
