PROBLEM TO BE SOLVED: To provide a curable composition which is easily cured by irradiation of active energy rays or heating, and of which the cured film is excellent in hardness and chemical resistance and also the environmental load is small. SOLUTION: The curable composition includes a (meth)acrylate (A) obtained from the polyol represented by formula (1). The component (A) preferably is a product of transesterification of the polyol represented by formula (1) with a (meth)acrylate, a product of an urethanization reaction of the polyol represented by formula (1) with an isocyanate group-containing (meth)acrylate, or a product of an urethanization reaction of the polyol represented by formula (1) with an organic polyisocyanate and hydroxy group-containing (meth)acrylate, or the component (A) preferably has a hydroxyl value of 10-300 mgKOH/g.
