A resin-molded type photosensor such as a photointerrupter or a reflection-type photosensor is formed in a body of U-shape. Within the U-shaped resin package, a light emitting element and a light detecting element are provided to be electrically connected to a first external electrode and a second external electrode, respectively. Furthermore, a U-shaped electric conductive coupling member is provided within the package so as to electrically connect the first external lead, the light emitting element, the light detecting element and the second external lead in series. Moreover, a resistor element is provided within the package so as to be electrically connected to the light detecting element in parallel and thereby enabling the photosensor having only two external leads.
