    Abstract: A vehicle lamp is provided which includes an inner lens suitable for diffusion of light. A vehicle lamp is provided which includes: a luminous body configured to emit surface light; and an inner lens placed forward of a light output surface of the luminous body, in which first steps extending in one direction are formed on an input surface of the inner lens, and second steps extending in a direction orthogonal to the first steps are formed on an output surface of the inner lens. It is possible to uniformly diffuse incident light in all directions by orthogonally forming the steps extending in the one directions on the two opposing surfaces, the input and output surfaces, of the inner lens. In addition, mold processing for injection molding is easy. Therefore, the reproducibility is also high.
