A vehicle lamp includes a light source and a plate-shaped light guide including a first plate surface on which a plurality of reflective elements are formed and a second plate surface. The plate-shaped light guide is configured to totally reflect light from the light source by the plurality of reflective elements. The plurality of reflective elements are arranged in a state of being continuously arranged along a line extending in a direction, and are arranged in a plurality of rows on the line. The plate-shaped light guide is configured to allow the light from the light source to reach a position of the line from a first direction. Each of the reflective elements has a substantially concave curved surface shape, and as compared to reflective elements constituting a first row, reflective elements constituting a second row is formed at a deeper position from the first plate surface.
