Abstract
To provide a detector capable of reliably inducing a gas containing a detection target to a detection space. A detector which is attached to an installation surface of an installation target and has an attachment surface facing the installation surface includes a detection space into which a detection target flows; a light-emitting portion and a light-receiving portion which detect the detection target flowing into the detection space; a casing which accommodates the light-emitting portion, the light-receiving portion and the detection space; and a rib, an inclined surface, a light shielding portion, a casing side inflow opening, a substrate side outflow opening, a casing side outflow opening, a back plate, and the like which induce gas outside the casing, which is gas containing the detection target, to flow into the detection space inside the casing from an opposite side of the attachment surface of the casing and to flow out from the side of the attachment surface of the casing in a direction substantially orthogonal to the attachment surface.
