Claim Text:
1. An optical member formed of resin, comprising a fixation portion, via which the optical member is fixed to a supporting member on which a light emitting element is supported; a reflective surface having a reflective region configured to reflect light from the light emitting element; and a thermal deformation absorbing portion configured to absorb thermal deformation of the optical member, wherein the thermal deformation absorbing portion is provided between the reflective region and the fixation portion, wherein the thermal deformation absorbing portion is a gap portion formed between the reflective surface and the fixation portion, wherein the optical member further comprises: wherein the fixation portion and the thermal deformation absorbing portion are provided in the arm part, wherein the reflector body is thermally deformed toward the fixation portion for the supporting member by narrowing clearance of the gap portion when the reflector body receives heat of the light emitting element from the supporting member and therefore is thermally deformed, and wherein the gap portion is formed along a boundary of the reflector body and the arm part from one end of the arm part.
