<p>A hydrophilic member includes a base material; and a layer containing a hydrophilic material (1) and an oligomer or polymer (2), the layer is a composition gradient layer in which a composition of (1) and (2) continuously changes in a thickness direction of the layer in such a manner that a ratio of (1) becomes large, whereas a ratio of (2) becomes small, from the nearest side to the base material toward the farthest side to the base material, the hydrophilic material (1) is a hydrophilic material containing a hydrolyzable silyl group-containing hydrophilic polymer, the polymer having at least one hydrolyzable silyl group represented by the formula (a) as defined herein at a main chain end or side chain of a molecule thereof and having at least one hydrophilic group in the molecule, and the oligomer or polymer (2) is different from the hydrophilic polymer (1).</p> |
