Abstract
According to one aspect of the present invention, an organic fluorine compound is represented by a general formula (R-π-E-CH2)2-A (1A) (where A is a divalent perfluoropolyether group, π is an arylene group or a single bond, R is an alkenyl group or an alkynyl group, and E is an ether bond or an ester bond or a group that is represented by a chemical formula —O—CH2CH(OH)CH2O— two groups each of which is represented by a general formula R-π-E-CH2— may be the same or different, and at least one n among two π is an arylene group).
