Problems:

There is a technology using the reflected light which is emitted from the light-emitting element and reflects without being absorbed in the inside of the optical bench, in order to detect whether the light-emitting element and the light-receiving element normally function. In this case, they do not normally function when there is either too little or too much reflected light in the inside of the optical bench. It is therefore an object of the present invention to achieve a suitable amount of reflected light inside the optical bench.

Means for solving the problems:

A light-receiving element 93 and a first light-emitting element 91 are disposed in a position in which the light-receiving element 93 receives forward-scattered light produced when smoke in the smoke detection part 10 is irradiated with first irradiation light emitted from the first light-emitting element 91. A secondary reflecting plate 716 is provided on a side of the first light-emitting element 91 inside the peripheral wall. The secondary reflecting plate 716 is configured to form secondary reflected light when the smoke detection part 10 without smoke is irradiated with the first irradiation light. The secondary reflecting plate 716 receives primary reflected light resulting from reflection of the first irradiation light from the peripheral wall and reflects the primary reflected light, and then allows the formed secondary reflected light to enter the light-receiving element 93.
