An optical sensor comprises a sensor circuit having parts which are optically interconnected with each other through an optical interconnection board interposed therebetween. The interconnection between the sensor circuit parts is thereby simplified remarkably, so that the mass-producibility of the sensor can be increased to lower its manufacturing costs.
