To provide a hydrophilic member which has excellent adhesiveness, allows the surface of a base material to be excellent in water resistance, antifogging properties, antifouling properties and weatherability and have hydrophilicity, and has a composition gradient structure.
The hydrophilic member 1 has the base material 2 and a film which is arranged on the base material 2 and contains a hydrophilic material (1) and an active energy ray-curable oligomer or polymer (2)'. The film is a composition gradient film 3 in which the composition of the hydrophilic material (1) and that of the active energy ray-curable oligomer or polymer (2)' change continuously in the thickness direction thereof so that a ratio of the hydrophilic material (1) may become larger and that of the active energy ray-curable oligomer or polymer (2)' may become smaller as it goes from the closest side thereof to the base material 2 to the farthest side thereof from the base material. The active energy ray-curable oligomer or polymer (2)' is different from the hydrophilic material (1). The hydrophilic material (1) contains a hydrolyzable silyl group-containing hydrophilic polymer having at least one hydrolyzable silyl group at the terminal of a main chain or a side chain of one molecule thereof and at least one hydrophilic group in one molecule thereof.
