1. A surface treatment film provided on a surface of a substrate, the surface treatment film having a laminated structure comprising a polymer layer (i) disposed on a surface side of the substrate and a polymer layer (ii) disposed on the polymer layer (i), wherein
the polymer layer (i) comprises a first polymer derived from at least one polymerization initiation group-containing polymer selected from the group consisting of a polyester, a polyurethane, a polyamide, a polyimide, and a polyepoxy each having, in a side chain, a functional group that functions as a polymerization initiation group and is represented by the following formula (1), and in the polymerization initiation group-containing polymer, a content of the functional group represented by the formula (1) is 0.5 mmol/g or more,
the polymer layer (ii) has a film thickness of 200 nm or more, and
the polymer layer (ii) comprises a second polymer comprising a constituent unit derived from at least one monomer selected from the group consisting of an aromatic vinyl-based monomer, a (meth)acrylate-based monomer, and a (meth)acrylamide-based monomer and extending using the functional group represented by the following formula (1) as a polymerization initiation point:
