1. A light-emitting unit comprising:
a light source; and
a lens body disposed in front of the light source,
wherein the lens body includes:
a projection lens part that is constituted by a convex lens, a focal distance of which is provided such that a rear side focus of the convex lens coincides with the light source or a vicinity of the light source and that is configured to project a graphic pattern, which transmits a form provided by light emission of the light source toward a road surface; and
a light emission lens part configured to surround the projection lens part and emit light from light emitted from the light source,
wherein the light emission lens part includes an incident surface that is located on a side facing the light source and that is configured such that light emitted from the light source enters into the light emission lens part, and a light emission surface that is located on a side opposite to the incident surface and that is configured to emit the light entering from the incident surface to outside,
a side of the projection lens part facing the light source and a side of the light emission lens part facing the light source are both constituted by a flat surface, such flat surface continuous with the incident surface,
the convex lens is provided so as to protrude forward from the light emission surface from the side opposite to the incident surface, and
at least some of light emitted from the light emission surface is emitted in a direction different from a direction of light emitted from the projection lens part.
