PROBLEM TO BE SOLVED: To provide a fire sensor which can easily inspect product and has a fast connecting terminal that is easy to be inserted through a through hole of ceiling. SOLUTION: The sensor is composed in a manner such that a fast connecting terminal 3 is connected through a lead wire 2 to a sensor main body 1, and the terminal 3 is provided projectingly with a terminal 5 for inspection that is electrically connected to its electrode 4. A constricted part 6 is formed at the base part of the terminal 5, and a chamfer 7 is formed on the face where the wire 2 of the terminal 3 extends. In the sensor, because the terminal 5 is projected from the case 8 of the terminal 3, inspection can easily be performed by connecting the projecting terminal 5 with a tester in the case of inspection when manufactured or the like. Also, in the case of extracting the terminal 3 pushed into a space in a building between the ceiling and the roof through the through hole after the work execution, it is possible to easily extract the terminal 3 because the terminal 3 is made to hardly hooked in the through hole of the ceiling.
