PROBLEM TO BE SOLVED: To provide an active energy ray-curing composition which is a composition comprising a polymerizable compound having a polyethylene glycol chain and forming a cured film scarcely deteriorating the polyethylene glycol chain by oxidation even when exposed to high-temperature environments over a long time and holding high hydrophilicity or anti-fogging properties over a long period. SOLUTION: The active energy ray-curing composition comprises an active energy ray-curing compound (a), one or two or more kinds of metal salts (b) selected from a metal perchlorate, a metal trifluoromethanesulfonate, a metal tris(trifluoromethanesulfonyl)methide, a metal thiocyanate and a metal nitrate and an active energy ray-curing compound (c) other than the compound (a). The active energy ray curing compound (a) has (i) a phenyl group substituted with a 6-20C alkyl group which may have a branched chain, (ii) a group represented by a -(CH<SB>2</SB>CH<SB>2</SB>O)<SB>n</SB>- (wherein, n represents an integer of 6-20) and (iii) an acryloyl or a methacryloyl group in the same molecule.
