To provide a curable composition which gives a cured fluorinated product excellent in transparency, light resistance (particularly against a short wavelength light having a wavelength of from 200 to 500 nm) and heat resistance, and having a controlled volume particularly thickness. A curable composition which contains a perfluorocyclic polyene having alicyclic structures which comprise carbon atoms and which may contain an oxygen atom and having at least two carbon-carbon double bonds, at least one of which is a polymerizable carbon-carbon double bond in which at least one of the two carbon atoms forming the polymerizable carbon-carbon double bond is a carbon atom forming the alicyclic structure, and a polymerization initiator; a cured fluorinated product obtained by curing the curable composition; an optical material made of the cured fluorinated product; and a light emitting device encapsulated with the cured fluorinated product in a light-transmitting manner. |
