Abstract

PURPOSE:To enable an identification code to be provided through a simple process by providing an identification code, which is made of the same material as a color filter and has a different optical characteristic, outside the effective image pickup area on a glass base plate. CONSTITUTION:After a photosensitive paint film 5 is formed over the entire surface of a light transmitting glass base plate 1, an identification code formation mask which consists of a stripe filter and an identification code is placed on the paint film 5. Next, they are exposed to ultraviolet rays and washed with water so as to form a stripe filter formation gelatin film 6a and an identification code formation gelatin film 66 which have desired shapes simultaneously. After that, the film 6a is dyed into a desired color so as to make a stripe filter 7, and the filter 7 is coated with a protective body 8. In addition, the film 6b is heated so as to make so identification code 9.
