PROBLEM TO BE SOLVED: To provide a plate glass with an ultraviolet-shielding coating film capable of reducing the amount of ultraviolet to pass through, a production method thereof, and a coating liquid for forming the coating film.SOLUTION: In a plate glass with an ultraviolet-shielding coating film, the coating film contains an ultraviolet absorber. The coating film is obtained by applying a coating liquid on the plate glass and curing the coating liquid. The coating liquid is obtained by mixing: the ultraviolet absorber; a reaction product obtained by reacting (a) a silane compound containing an amino group represented by general formula [1] of RSi(OR), in which Rrepresents an organic group containing an amino group, Rrepresents a methyl group, an ethyl group or a propyl group, and n represents an integer selected from 1 to 3, and (b) at least one kind of boron compound selected from the group consisting of HBOand BO; (c) metal alkoxide and/or a condensate thereof; (d) synthetic resin; and a solvent compos
