Abstract
A vehicle lamp includes a light source and a plate-shaped light guide body. The plate-shaped light guide body is configured to totally reflect light from the light source that is incident on the plate-shaped light guide body by a plurality of reflective elements formed on a first plate surface of the plate-shaped light guide body, and then, to emit the light from a second plate surface of the plate-shaped light guide body toward the front side of the vehicle lamp. The plurality of reflective elements are disposed in a state of being continuously arranged along a line extending in a required direction. Each of the reflective elements has a substantially concave spherical surface shape or a substantially convex spherical surface shape.
