An object of the present invention is to provide a care environment, which can be easily handled in a small number of steps, and at a low cost, as a new base for the treatment step before electroless plating. The solution of the present invention is a base for forming a base for a metal plating film on a substrate by electroless plating, which has an ammonium group at a molecular terminal and a weight average molecular weight of 500 to 5,000,000. Highly branched polymers, and metal microparticles. |
