摘要：An occurrence space 32A which is provided in a light shielding space 3A shieldedfrom light from an outside and into which a detection target flows, a first light emitting

unit 61A and a second light emitting unit that emit detection light along a first lightemitting-side optical axis 611A and a second light emitting-side optical axis toward anoccurrence space 32A, a light receiving unit that receives scattered light generated whendetection light emitted from the first light emitting unit 61A and the second lightemitting unit is scattered by a detection target flowing into the occurrence space 32Aalong a light receiving-side optical axis intersecting the first light emitting-side opticalaxis 611A and the second light emitting-side optical axis, and a smoke detection unitcover-side inclined portion 43A that primarily reflects the detection light emitted fromthe first light emitting unit 61A and the second light emitting unit in a direction

intersecting a plane defined by the first light emitting-side optical axis 611A, the secondlight emitting-side optical axis, and the light receiving-side optical axis are included.
