Abstract: A curable composition containing: a methylene malonate compound, and a Lewis acidic compound. The methylene malonate compound is preferably a compound represented by formula (1) or formula (2). In the formulae (1) and (2), X1 to X4 each independently represent O, NR, or C(R)2, R's each independently represent a hydrogen atom, an alkyl group, or an aryl group, R1 and R2 each independently represent an alkyl group or an aryl group, and R3 represents an alkylene group, an arylene group, or a group obtained by combining two or more of these groups.
