PROBLEM TO BE SOLVED: To provide a conductive substrate capable of easily forming a metal film on a substrate without heating and performing optical treatment. SOLUTION: In the conductive substrate (a metal composite film) formed of the substrate and the metal film formed on the substrate, the substrate is to be a substrate having a porous layer (for example, a porous layer formed of inorganic particles such as silica) at least on the surface, dispersion liquid including metal colloid particles composed of metal nano-particles A and protective colloids B for coating the metal nano-particles A is coated on the porous layer to form the metal film, and thus, the metal composite film is manufactured. Low temperature sintering of the metal nano-particles can be produced on the conductive substrate by only applying the dispersion liquid. COPYRIGHT: (C)2009,JPO&INPIT
