The present invention provides an environment that can be easily handled in a small number of steps, and can be reduced in cost, and in particular, the substrate to be coated with a metal film is excellent in adhesion, and can be used as a novel processing step before electroless plating. Base agent.nThe base agent of the present invention is a base material for forming a metal plating film by electroless plating, comprising (a) a super-branched polymer having an ammonium group at a molecular terminal and having a weight average molecular weight of 1,000 to 5,000,000. (b) metal fine particles, and (c) a resin primer for electroless plating. |
