To form a highly precise pattern for dielectric by exfoliatively providing a transfer layer which contains a prescribed inorganic and organic components and has a specific surface grossiness degree on a base film and by setting its surface grossiness degree after exfoliating a protective film provided on the transfer layer to a specific range.

A transfer layer 13 containing an inorganic component containing glass frit and an organic component removable by burning is formed on a base film 12 such as a resin film. Then, the surface glossiness degree is set within 20-110 according to the setting of the powder shape and the content of the inorganic component, types and the content of the organic components, solvent, and coating conditions. A soft protection film hard to deform such as a polyethylene film is formed on the transfer layer 13 and the surface performance or the surface glossiness degree of the transfer layer 13 after exfoliating the protection film 14 within the range 30-110 is provided therewith. This constitution eliminates any aggregate or pinhole formed in the transfer layer and eliminates any bubble formed between the transfer layer and the protection film so as to hold the superior surface smoothness.
