Abstract
A collimator lens in use for a vehicle lighting apparatus includes: an incident surface which allows incident light to become primary light that passes through an inside of the collimator lens; and an emission surface that is configured to emit secondary light parallel to an optical axis of the collimator lens, wherein a diffusion angle of a horizontal component of the primary light is larger than a diffusion angle of a component in a vertical direction of the primary light.
