color filter 13 comprises first second and third filter element arrays 13a 13b and 13c and transparent inter level films 13d and the transparent inter level films 13d covers the first second and third filter element arrays 13a to 13c respectively the first second and third filter element arrays 13a to 13c are different in spectrum characteristics to visible light from one another the first and second filter element arrays 13a and 13b are provided over the third photo electric converting element sub array 123 and the second and third filter element arrays 13b and 13c are respectively located over the first and second photo electric converting element sub arrays 121 and 122 a transparent inter level film 16 covers the optical color filter 13 and creates a smooth top surface the protective filter film 14 is formed on the smooth top surface of the transparent inter level film 16 the protective filter film 14 is formed of casein and the casein film is colored by using transparent dye of naphthalene compound benzophenone compound or phenol compound the protective filter film 14 has a predetermined absorption spectrum and accordingly effectively absorbs a predetermined wavelength region close to the ultra violet region outside the visible light region in this description the visible light region ranges from 400 nanometers to 700 nanometers if.
