To provide a hardly colored curable composition having an excellent storage stability while maintaining fast curing properties. A curable composition which comprises a polymer (P) having a polyoxyalkylene chain and a group of the following formula (1) and a compound (S) having a mercapto group and a group of the following formula (2), and which contains from 0.01 to 0.50 part by mass of the compound (S) per 100 parts by mass of the polymer (P): <?in-line-formulae description="In-line Formulae" end="lead"?>-Si(-X<SUP>1</SUP>)<SUB>3</SUB> (1)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>-Si(-X<SUP>2</SUP>)<SUB>m</SUB>(-Y<SUP>2</SUP>)<SUB>3-m</SUB> (2)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein symbols have the following meanings: X<SUP>1 </SUP>and X<SUP>2</SUP>: each independently a C<SUB>1-6 </SUB>alkoxy group, Y<SUP>2</SUP>: a C<SUB>1-6 </SUB>alkyl group, and m: 1, 2 or 3.
