PROBLEM TO BE SOLVED: To provide an active energy light-curable composition having excellent curability. SOLUTION: This active energy light-curable composition comprises (A) 5 to 100 pts.wt. of a sulfur-containing compound prepared by reacting (a) a compound of the formula [R1, R2 and R3 are each identically or differently methyl group, ethyl group or propyl group; (n) is an integer of 1 to 8] with (b) an acrylic unsaturated compound containing two or more (meth)acryloyl groups on the average in one molecule and having an average mol.wt. of 150 to 2,000 in a thiol group (SH)/unsaturated group molar ratio of 0.5 to 1.2, (B) 0 to 95 pts.wt. of a photocation-reacting compound, (C) a photocation polymerization initiator in an amount of 0.05 to 20 pts.wt. per 100 pts.wt. of the total amount of the components A and B, and (D) a photoradical polymerization initiator in an amount of 0 to 20 pts.wt. per 100 pts.wt. of the total amount of the components A and B.
