PROBLEM TO BE SOLVED: To provide a fire alarm capable of compatibly attaining thinness, compactness, and fire detection speed in an effective manner.SOLUTION: A thermal fire alarm 1 has a thermal detection part 26 on a top end part 25a of a thermal detection sensor 25. The top end part 25a of the thermal detection sensor 25 is arranged between a front wall part 15 facing the front side in a case 10 and a surface panel 31. An atmosphere intake port 32 is provided at the place faced by the top end part 25a of the thermal detection sensor 25 in the surface panel 31. The thermal fire alarm has a case concave part 16 and a surface panel concave part 33 provided on the front wall part 15 of a case 10 and the rear face 31a of the surface panel 31 so as to surround the thermal detection sensor 25 in the front view. |
