摘要：
A light emission element array comprises a substrate, a plurality of light emission elements such as light emitting diodes aranged linearly in a row on the substrate and a rod like, i.e., columnar, light converging lens unit arranged above the light emission element row in parallel thereto and adapted to diffuse and simultaneously converge the transmitted light. The light emitting surface of the light converging lens unit is made rough by a chemical treatment, blast treatment or other means.
