Abstract

A film for a microfluidic device is capable of bonding to a polydimethylsiloxane substrate having flow channels formed in a surface thereof, and also exhibiting stable hydrophilicity even under high temperature and high humidity conditions and having scratch resistance. When the film can be used as a microfluidic device, the film is bonded to a polydimethylsiloxane substrate having flow channels formed in a surface thereof to form a liquid-tight flow channels. The film including a base material and a hydrophilic coating, wherein the hydrophilic coating includes a (meth)acrylic resin and from 65 to 95 mass % of unmodified nanosilica particles based on a total mass of the hydrophilic coating.
