Abstract
PURPOSE: To make it possible to form a conductive film with reduced deterioration of its junction strength with a base plate by including glass powder and/or bismuth oxide powder as surfaces of their particles are coated with Pd powder.
CONSTITUTION: In a composition, the surface of particles of glass powder and/or bismuth oxide powder are coated with Pd powder. Coating on glass powder and bismuth oxide powder with Pd powder is achieved by a mixing machine which mixes them while roughly grinding them, but if a particle diameter of the Pd powder is too large, the surface of the particles of glass powder and bismuth oxide powder can not be effectively coated, and if it is too small, the Pd powder easily coagulates, then this results in the same situation. Accordingly, deterioration of the junction strength of a conductive film with a base plate can be reduced and reliability of its junction can be enhanced.
