1. A vehicle lamp, comprising:
a white lamp; and
an illumination device for an active sensor, wherein
the illumination device includes:
a near-infrared light source; and
a photoconductor configured to receive emitted light from the near-infrared light source and emit, from an emission surface, illumination light having a predetermined light distribution,
the photoconductor is disposed such that a rear surface thereof faces a light emitting surface of the white lamp, and emits, from the emission surface, the emitted light of the white lamp which is received at the rear surface; and
the rear surface of the photoconductor is provided with a plurality of steps spaced apart in an optical axis direction of the near-infrared light source.
