Abstract
There is employed a lamination structure of semiconductor substrate in which light receiving part having a photoelectric converting function is formed in an inner portion, and insulating films and wirings. There are provided a wiring layer formed above semiconductor substrate and having a concave portion formed in a place corresponding to a portion disposed above light receiving part, second insulating film having a higher refractive index than insulating films and covering a side surface of the wiring layer facing the concave portion, third insulating film having a lower refractive index than second insulating film and covering the side surface of second insulating film, and fourth insulating film having a higher refractive index than third insulating film and covering the side surface of third insulating film.
