A surface mount type photo-interrupter includes an insulating base, a light emitting element and a light receiving element provided on the insulating base, a first terminal electrode for the light emitting element, a second terminal electrode for the light receiving element, a first primary mold which is transparent and covers the light emitting element, a second primary mold which is transparent and covers the light receiving element, and a secondary mold which is opaque and fixes the first and second primary molds. Each of the first and second terminal electrodes is formed at a side surface and/or a lower surface of the insulating base. The secondary mold is provided with a groove located between the first and second primary molds. Light from the light emitting element passes across the groove to reach the light receiving element.
