A lens frame for fixing a lens in place using an adhesive, the lens being disposed on a reference axis line, in a state in which the position of the lens is adjusted in at least an axis direction along the reference line, wherein the lens frame is provided with: an axis-direction receiving unit provided so as to be able to abut the lens in the axis direction in order to set the orientation of the lens with respect to the reference axis line, the axis-direction receiving unit being separated from the lens when the lens is fixed; an adhesive guide surface for forming a gap between the adhesive guide surface and a side surface of the lens in a radial direction perpendicular to the reference axis line, an adhesive being introduced into the gap; and an adhesive stopping portion provided between the adhesive guide surface and the axis-direction receiving unit in the axis direction, the adhesive stopping portion engaging with the side surface of the lens in the radial direction when the lens abuts the axis-direction receiving portion, and stopping the adhesive introduced into the gap such that the adhesive does not flow to the axis-direction receiving unit. |
