A reflection-type optical sensor package is provided to prevent an increase of the volume of a final product by including one light emitting or receiving device and a plurality of light receiving or emitting devices. One central device(120) is mounted on the center part of the surface of a printed circuit board. A plurality of outer devices(130) are mounted in the periphery of the printed circuit board with respect to the center of the printed circuit board. The central device and the outer device are isolated from external surroundings by a first molding part(140) for protecting the central device and the outer device. A second molding part(150) optically isolates the central device and the outer device, formed in the circumference of the central device. One of the central and outer device can be a light emitting device, and the other one of the central and outer device can be a light receiving device.
