Provided is a hydrophilizing treatment agent capable of forming a hydrophilic coating film in which the preferred hydrophilicity and antifogging properties are obtained and which has exceptional moist heat resistance and scratch resistance. A hydrophilizing treatment agent that includes: a hydrophilic polymer (A) having at least one of an alkoxysilyl group and a hydrolysate thereof, and also having a betaine structure, in each molecule; and a hydrophilic polymer (B) that is a hydrophilic polymer having an ionic functional group and/or a non-ionic hydrophilic polymer. B/(A+B) is 1.0-51.0%. The preferred moist heat resistance and scratch resistance of the hydrophilic coating film formed by the hydrophilizing treatment agent are obtained due to the hydrophilic polymer (A) and the hydrophilic polymer (B) forming an ionically crosslinked network or a dipole-dipole interaction network.
