PROBLEM TO BE SOLVED: To provide a thermal fire alarm capable of suppressing the reduction of a fire detection speed when an atmosphere is made to flow from a specific direction and making a fire detection speed uniform even if the atmosphere flows from any direction.SOLUTION: A thermal fire alarm 1 is arranged with a plurality of support parts 34a to 34d which mutually fix a front wall part 15 facing the front side in a case 10 and a surface panel 31 at intervals from each other on a circumference E with the thermal detection sensor 25 as a center in the front view. The thermal fire alarm 1 is arranged along the inner side of the circumference E between the mutually adjacent two support parts 34, and includes a plurality of rectangular shaped introducing poles 17a to 17h which are set upright on the front wall part 15 of the case 10 so that the width direction of the introducing poles faces the thermal detection sensor 25. |
