  In the present invention, there is provided a hydrophilic monolayer film that is excellent in antifogging properties, antifouling properties, the durability of antifogging properties and antifouling properties, and smoothness and that has an antireflective function or a surface structure that serves as a polarizer. There is also provided a method for easily producing such a monolayer film. The monolayer film that is to be produced has a surface structure with multiple protrusions and depressions. The distance between the peaks of adjoining protrusions among such multiple protrusions is in the range of 1 nm to 800 nm. The monolayer film is formed of a crosslinked resin produced by curing of a polymerizable composition that contains a compound having a specific hydrophilic group and a functional group with a polymerizable carbon-carbon double bond and a compound having two or more (meth)acryloyl groups. A gradient of the concentration of hydrophilic groups (Sa2/Da2) in the monolayer film is not less than 1.1 wherein Sa is the concentration of at least one type of hydrophilic groups selected from anionic hydrophilic groups, cationic hydrophilic groups, and a hydroxyl group at the top layer, and Da is the depth concentration of the hydrophilic groups at 1/2 of the thickness of the monolayer film.
