低減することができる。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In Fig. 2, 1 is a color solid-state image sensor for a video color camera, 3 is an infrared cut filter attached to the periphery of the surface of the color solid-state image sensor 1 using adhesive, etc., and 4 is an infrared-cutting filter. According to the present embodiment configured as described above, which is a crystal Savard plate that prevents optical interference and constitutes a color solid-state imaging device for video color cutting, the infrared cuff filter 3, By simply using two crystal Savart plates 4, all the functions of protecting the surface of the color solid-state image sensor 1, preventing optical interference, and removing infrared rays can be performed, and the protection glass 2 can be used as in the conventional case. This makes it possible to reduce the number of parts used and reduce costs.
