Abstract: A lighting apparatus includes: a projection lens; a light source behind the projection lens; a reflector that reflects light from the light source toward the projection lens; and a shield that blocks a portion of the light reflected by the reflector to form a cutoff line in a distribution pattern of the light. A textured section demarcated by unit regions is formed on a surface of the projection lens, and when a region in a center of the projection lens is defined as a central region, and regions left and right of the central region are defined as left and right regions, respectively, in a front view, a proportion of the unit regions in the central region is greater than a proportion of the unit regions in each of the left region and the right region.
