A light guide 1 is provided at the reverse side thereof with triangular uneven surfaces 1 b at a predetermined pitch. The uneven surfaces 1 b are integrally formed with the light guide 1 when the latter 1 is injection-molded. Incident light from a light incident plane is caused to be totally reflected within the light guide and to spread in a main scanning direction (the longitudinal direction), wherein the light reaching the uneven surfaces 1 b is scattered and caused to be totally reflected at the uneven surfaces 1 b . The light scattered and totally reflected at the uneven surfaces 1 b is emitted from an emission plane. Intensity of light in the main scattering direction can be made uniform by lengthening the uneven surfaces 1 b as the uneven surfaces extend from the light incident plane. A position where the light intensity becomes maximum in a sub-scanning direction can be changed by adjusting an angle between the ridgeline of the uneven surfaces 1 b and the sub-scanning direction, and distributed characteristics of the light intensity in the sub-scanning direction can be also changed.
