Filed: 1990-11-27
Abstract: PURPOSE:To prevent the generation of a migration of silver by a method wherein a circuit conductor is formed of silver conductor consisting of a silver paste, and an insulating layer of the same quality as that of an insulating film is formed on the surface of the formed circuit conductor by a dry process. CONSTITUTION:Silver conductors 102 on an insulating film 101 are formed of a silver paste by a screen printing and a fine circuit pattern of a high conductivity is formed. An insulating layer 103 which is formed on the conductor 102 is formed by a dry process.
