A fundamental surface for a reflection surface of a reflection mirror of a vehicle lamp is formed in a manner such that a curved surface where an insertion hole, through which a light source is inserted into the reflection mirror in the direction oblique to the optical axis of the reflection mirror, is to be formed, is made smoothly continuous to the remaining curved surface without any level-difference. A group consisting of a number of paraboloids of revolution with different focal distances are put on the fundamental surface, and a group of closed curves formed as intersecting lines of the fundamental surface and the group of paraboloids of revolution are determined. A number of reflection steps in the form of loop are formed on the reflection surface. The reflection steps between the adjacent ones of the closed curves are defined by portions of the paraboloid of revolution between the adjacent ones.
A vehicle lamp comprising a reflection mirror having an optical axis, said reflection mirror comprising:
