PROBLEM TO BE SOLVED: To reduce the manufacturing cost of a light receiving panel device by reducing the number of components. SOLUTION: A light receiving panel device 2 is constituted in such a way that a panel 4 with light receiving window is put in the opening 3 of an enclosure 1 and a receiver 13 is attached to a substrate 12 arranged in the rear of the panel 4 so that the receiver 13 may receive infrared signals emitted from a transmitter through the light receiving window. The panel 4 has a light- transmissive panel main body 4A which is put in the opening 3 and a light- transmissive film 4b stuck to the surface of the main body 4A. On the rear surface of the film 4B, in addition, a light shielding mask which covers the film 4B except the light receiving window and an infrared-ray transmitting film which covers the light receiving window are printed. |
