Abstract:
1. A temperature sensor, comprising: a front surface; a back surface; a first temperature-sensitive element and a second temperature-sensitive element disposed side by side between the front surface and the back surface; an infrared-ray absorber; and a heat-transfer inhibitor, wherein, when the temperature sensor is exposed to infrared rays that have propagated from both of a front-surface side and a back-surface side, the infrared absorber heats up by absorbing the infrared rays and transfers heat to the first temperature-sensitive element and the heat-transfer inhibitor inhibits heat transfer to the second temperature-sensitive element caused by the infrared rays, wherein the infrared-ray absorber is a substrate on which the first temperature-sensitive element and the second temperature-sensitive element are mounted, and wherein the heat-transfer inhibitor includes infrared-ray reflectors disposed at a front-surface side and a back-surface side of the second temperature-sensitive element.
