A process for producing a filter comprising: a step of arranging an electrodeposition substrate, which comprises a light transmissible support having a light transmissible conductive film and a photosemiconductor thin film with a photoelectromotive function in this order provided thereon, in such a manner that at least the photosemiconductor thin film is immersed in an electrodeposition solution containing a colored electrodeposition material; a step of imagewise exposing the electrodeposition substrate with applying a voltage or an electric current to the conductive film, to form a colored electrodeposition film in an exposed part; a step of immersing at least the photosemiconductor thin film, in which the colored electrodeposition film has been formed, of the electrodeposition substrate in a metallic plating solution; and a step of applying a voltage or an electric current to the conductive film, to form a black matrix comprising a metallic plating film in a part of the photosemiconductor thin film, in which the colored electrodeposition film is not formed. The black matrix of the metallic plating film may be formed before the formation of the colored electrodeposition film.
