The second imaging optical system has at least one optical function surface on which an optical function portion including a plurality of convex portions arranged therein so as to have a serrate cross section is formed in at least part thereof. The optical function surface is formed so that a width of each of the convex portions in an arrangement direction in which the convex portions are arranged is larger than a width of the laser light flux in the arrangement direction, which enters the optical function surface.

摘要： The present invention relates to a surface light source, including a light source section made up of plural light emitting diodes and lenses that expand light from these light emitting diodes. The lens in the light source section has a light incident surface on which light from the light emitting diode is incident with an optical axis at a center, and a light exit surface that expands and emits the incident light. The light incident surface has a continued depressed surface, while the light exit surface has a continued projected surface. The lens performs such that “sag Y” decreases from a maximum value “sag Y0” with an increment of “θi”, where θi is an angle included between a straight line, connecting an arbitrary point on the light exit surface and a base point on the optical axis which corresponds to a position of the light emitting diode, and the optical axis; sag Y is a distance measured in a light axis direction from the base point on the optical axis to the arbitrary point on the light exit surface; and “sag Y0” is a value of sag Y when angle θi is 0 (zero) degree, and wherein the light exit surface except a vicinity of the optical axis takes a shape satisfying a relation of 10 degrees
