In FIG. 2, 1 is a color solid-state image sensor used in a video color camera, etc., and 6 is a filter layer for cutting infrared rays formed by vapor deposition or sputtering IJ.
It is an infrared cut crystal Savart plate that prevents optical interference.
It is attached to the surface of the color solid-state imaging device 1 using an adhesive or the like, and the above constitutes a color solid-state imaging device for a video color camera.

Further, unlike the conventional case, the surface protection glass 2 and the infrared ray cutting filter 3 are not required, and therefore, the number of parts used can be significantly reduced, and costs can be reduced. Furthermore, since the area to which dust and the like due to static electricity adhere during assembly can be significantly reduced, light transmittance can be improved, and thereby focus performance can also be improved.
