Abstract
An automotive lamp includes an LED, a substrate that mounts the LED, a reflector that reflects the light emitted from the LED, and an projection lens having an incident surface, which receives the light reflected by the reflector, and an emission surface that emits the light toward a front area of the automotive lamp. A fine asperity structure is formed on the incident surface of the projection lens. The fine asperity structure includes recesses or raised portions formed with the pitch less than or equal to the visible light wavelength.
