PURPOSE:To obtain a curable composition useful as a molding material, an adhesive or the like, by mixing 3,9-diallyl-1,5,7,11-tetraoxaspiro[5.5]undecane, a polythiol and a radial polymerization initiator as essential components together. CONSTITUTION:The purpose curable composition is prepared by mixing 3,9- diallyl-1,5,7,11-tetraoxaspiro[5.5]undecane (A) of formula I, a thiol (B) of formula II (wherein R is a polyvalent organic group and n>=3) and a radical polymerization initiator (C) (e.g., azobisisobutyronitrile) as essential components together. It is suitable that the ratio of (the number of moles of component A X 2) to (the number of moles of component B X the number of mercapto groups per molecule of component B) is 0.6-1.8 and that the amount of component C is 0.001-20mol.% based on the total of components A and B.
