PROBLEM TO BE SOLVED: To improve the noise proof of an optical sensor, and facilitate its development into other kinds of devices, and further, reduce the necessary time and cost of the development. SOLUTION: A bare chip 3 whereinto a photo diode, amplifying circuit, and oscillating circuit are integrated, a coupling capacitor 4 connected with the amplifying circuit, and a resistance 5 for oscillating frequencies whereby the oscillating frequency of the oscillating circuit is specified are so mounted on a packaging substrate 2 and they are so sealed by a transparent resin as to constitute out of them a light receiving package 1 for the optical sensor and as to mount it on a secondary mounting substrate 9.
