TEMPERATURE SENSOR AND TEMPERATURE SENSOR ARRAY

Provided is a temperature sensor that is excellent in load bearing capability and can obtain high temperature detection accuracy. Disclosed is a temperature sensor including a sensor unit formed on a flexible substrate, the flexible substrate including a first portion which is located at an end portion of the flexible substrate and in which the sensor unit is formed, and a second portion adjacent to the first portion in a distal direction from the end portion and having a maximum thickness between a first surface and a second surface facing each other, a surface of the first portion opposite to the sensor unit and the first surface of the second portion being on the same plane, at least the first surface of the second portion forming a detection surface in contact with an object whose temperature is to be detected, and a total thickness of the first portion and the sensor unit having a thickness smaller than the maximum thickness of the second portion.
