Abstract

A method for selectively modifying a base material surface, includes applying a composition on a surface of a base material to form a coating film. The coating film is heated. The base material includes a surface layer which includes a first region including a metal. The composition includes a first polymer and a solvent. The first polymer includes at an end of a main chain or a side chain thereof, a group including a first functional group capable of forming a bond with the metal. It is preferred that the base material further includes a second region comprising substantially only a non-metal, and the method further includes, after the heating, removing with a rinse agent a portion formed on the second region, of the coating film. The metal is preferably a constituent of a metal substance, an alloy, an oxide, an electrically conductive nitride or a silicide.
