Abstract:
To provide a heat detector in which thermal responsiveness of a heat detecting unit such as a ceramic element is improved.A heat detector 1 includes a ceramic element 10 accommodated in a sensing-device main body, and measures a temperature in a monitoring area based on a dielectric constant of the ceramic element 10. The Curie point temperature of the ceramic element 10 is set in a predetermined sensitive temperature range.
