PROBLEM TO BE SOLVED: To provide a highly transparent fluororesin applicable to obtain an antireflection film and free of reduction in molecular weight even when its production is carried out by direct fluorination treatment using fluorine gas, and to provide molded products, fine particles, and optical films containing the above resin. SOLUTION: This highly transparent fluororesin has a crosslinked structure, a chain formed by polymerization of polymerizable groups having carbon-carbon double bonds, and at least one kind of ring selected from the group consisting of aromatic rings and alicycles. The chain has at least one kind of fluorine-substituted methylene group selected from the group consisting of groups -CF<SB>2</SB>- and -CHF-. In at least a part of carbon atoms constituting the ring, a fluorine polymer, to which a fluorine atom is bonded, is contained. COPYRIGHT: (C)2010,JPO&INPIT
