Abstract
An optical unit has an optical element reflecting light between intersecting first and second directions, and a holder. The holder includes a holder body extending in a third direction intersecting the first and second directions, and a pair of surface portions extending from the holder body in an intersection direction intersecting the third direction. The optical element is arranged between the surface portions. At least one surface portion has an inner surface facing the optical element, an end surface connected to an edge of the inner surface in an intersection direction, and a concave portion arranged astride the inner and end surfaces and recessed in the intersection direction from the end surface. The concave portion accommodates an adhesive member bonding the optical element with the holder. The length of the concave portion along the end surface is greater than the depth of the concave portion in the intersection direction.
