Abstract
A light receiving element is formed by a plurality of light receiving cells connected in series with one another and arranged for optical coupling to a light source, the cells having respectively a surface area varied depending on light input intensity from the light source. The light receiving cells are thereby made to maintain excellent light receiving efficiency without causing optical loss at any one of them.
