Temperature sensing element and temperature sensing device having the same

摘要

The temperature detection element (1) of the present invention comprises a substrate (2, 3) having a substrate (4, 6) and electrodes (5, 7) disposed on the substrate (4, 6), A temperature detector (8) disposed on the substrate (4, 6) so as to be in electrical contact with the electrodes (5, 7), and an electromagnetic wave against a temperature change of the temperature detector (8). A change in absorption characteristics (light absorption characteristics) and a change in electrical characteristics (resistance value) are reversible. This temperature detection element (1) is easy to store and manage before use, and can detect temperature changes in the temperature management environment with high accuracy.
