<p>PROBLEM TO BE SOLVED: To provide a photcoupler in which an optical coupling route having no construction can be formed even by a small quantity of transparent resin and a high combination efficiency be ensured without increasing the thickness of a package. SOLUTION: In this photocoupler where two light receiving elements to one light emitting element are arranged with an equal interval of distance on the same plane as the light emitting element, one side facing the light emitting element of the light receiving element is inclined 45 degrees against one side facing the light receiving element of the light emitting element.</p> |
