Abstract

PURPOSE:To make it possible to obtain a pattern accurately dyed into a desired color by decoloring a colored photosensitive film by using a weak alkaline solution. CONSTITUTION:A solid-state image sensing element 8 having unevenness is coated with a mixture of a photosensitive material and an absorptive material which can be decolored by a weak alkaline solution to form a coating film 9, which is then exposed to ultraviolet rays 10 through a mask 11 and developed to remove the unexposed portion of the film 9. When there is some time between the film forming and the development, the film 9 is slightly colored. Then, being dipped in a weak alkaline solution, the film 9 is decolored. Then, the portion corresponding to the first color 12 is dyed by using a dye having given spectral properties to form a color filter. Thereafter, a transparent intermediate layer 13 is provided thereon for preventing mixture of colors. Moreover, operation similar to the first color is repeated to form color filters of and after the second color.
