Abstract
There is provided a vehicle lamp, the vehicle lamp including a light source that emits light, and a light-guiding component that includes (i) a light-guiding component main body having an end portion at one end in a longitudinal direction thereof through which light from the light source is guided in and having an emission surface from which light reflected by a step portion is emitted out, and also having pairs of inclined surfaces that, when looked at in a cross-sectional view taken in the longitudinal direction thereof, extend on an inclination relative to the emission surface and are disposed facing each other, a plurality of the pairs of inclined surfaces being disposed in the longitudinal direction, and (ii) differential refractive index layers that are interposed between the pairs of inclined surfaces and have a lower refractive index than the refractive index of the light-guiding component main body.
