Method for producing plated component, plated component, catalytic activity inhibitor and composite material for electroless plating

1. A method for producing a plated part, comprising:

forming, on a surface of a base member, a catalyst activity inhibiting layer containing a branched polymer having a side chain, the side chain including a group containing sulfur and an amide group;

irradiating with light or heating a part of the surface of the base member on which the catalyst activity inhibiting layer is formed;

applying an electroless plating catalyst to the surface of the base member heated or irradiated with the light; and

bringing an electroless plating solution into contact with the surface of the base member to which the electroless plating catalyst is applied, to form an electroless plating film at a light-irradiated portion or a heated portion of the surface.

2. The method for producing the plated part according to claim 1 , further comprising washing the surface of the base member after the part of the surface of the base member is heated or irradiated with the light and before the electroless plating solution is brought into contact with the surface of the base member.

3. The method for producing the plated part according to claim 1 , wherein the branched polymer is a dendritic polymer.
