PROBLEM TO BE SOLVED: To provide a resin composition which has an excellent storage stability and is, also, capable of preventing generation of cracking and whitening for a long period regardless of the thickness of its cured film. SOLUTION: The curable composition is characterized by containing a polyisobutylene-based polymer having at least one reactive silicon group (A), a photocurable compound having a number average molecular weight of >=400 (B), an air oxidation-curable compound (C) and a tertiary hindered amine-based photostabilizer (D).
