Imaging device having protruding optical member and sloped housing

An imaging device, comprising:

• an imaging element configured to receive subject light;
• an optical member configured to direct, to the imaging element, the subject light from an imaging range having a predetermined angle of view in at least a first direction;
• at least one illuminator including a light source configured to emit illumination light toward the imaging range and a cover covering the light source;
• and
• a housing including an outer plate on a plane intersecting with an optical axis of the optical member and a bottom surface facing the outer plate, the housing accommodating the imaging element and the at least one illuminator,
• wherein the predetermined angle of view includes a direction from the optical member toward the bottom surface in an area of the predetermined angle of view in at least one direction with respect to the optical axis of the optical member,
• the outer plate includes a slope with an inclination corresponding to the predetermined angle of view,
• the cover in the at least one illuminator is parallel to the slope,
• the outer plate includes the slope in at least one of two sides of the outer plate in a first direction with respect to a first reference position on a line extending, through the optical axis of the optical member, in a second direction orthogonal to the first direction, and
• the optical member protrudes from the outer plate in a direction away from the imaging element to a location where the slope of a first side of the at least two sides intersections the slope of a second side of the at least two sides.
