In the photointerrupter, the light emitting element and the light receiving element in the light emitting part are provided with a thin slit-like groove formed on the opposing sides of the light emitting part and the light receiving part so that light can pass therethrough. The light emitted from the light-emitting section is configured so that it can pass through the groove on the side surface of the light-emitting section and exit to the outside, and then pass through the groove on the side surface of the light-receiving section and enter the light-receiving element. A photo interrupter.
