The invention provides a hydrophilic member and a support for a planographic printing plate with a hydrophilic surface having hydrophilic graft chains and a cross-linked structure on a substrate surface formed by hydrolysis of an alkoxide of a metal selected from Si, Ti, Zr, and Al and condensation polymerization and it is characteristic that the hydrophilic surface contains a hydrophilic graft polymer, which is a copolymer of a macromer having hydrophilic functional groups and a structural unit having a silane coupling group. Further, the invention provides a hydrophilic graft polymer that is copolymer of macromers having hydrophilic functional groups and structural units having silane coupling groups.
