To provide a substrate having a metallic film capable of enhancing adhesivity between the substrate and the metallic film, and its manufacturing method.

A unimolecular film 2 is deposited between a substrate 1 and a metallic film 5. The single molecule film 2 is firmly bonded with the substrate 1 via a siloxane bonding. Since the pyrrolyl group having strong affinity to a metal is bonded with the metallic film 5, the adhesiveness between the substrate 1 and the metallic film 5 becomes more excellent. In the present embodiment, the surface of the substrate 1 is not lugged, the metallic film 5 worked in, for example, a wiring pattern is subjected to microfabrication in a desired shape with high accuracy.
