The invention claimed is: 1. An organic fluorine compound that is represented by a general formula (R-π-E-CH 2 ) 2 -A (1A) where A is a divalent perfluoropolyether group, π a is an arylene group or a single bond, R is an alkenyl group or an alkynyl group, and E is an ester bond or a group that is represented by a chemical formula —OCH 2 CH(OH)CH 2 O— two groups each of which is represented by a general formula R-π-E-CH 2 — may be the same or different, and at least one π a among two π a is an arylene group. 2. The organic fluorine compound according to claim 1 , wherein the A is a straight chain group. 3. The organic fluorine compound according to claim 1 , wherein a plurality of the R are the same. 4. The organic fluorine compound according to claim 1 , wherein a plurality of the π are the same. 5. The organic fluorine compound according to claim 1 , wherein a plurality of the E are the same. 6. The organic fluorine compound according to claim 1 , wherein a carbon number of the A is 1 to 100. 7. The organic fluorine compound according to claim 1 , wherein the A includes at least one of groups each of which is represented by a general formula —(CF 2 ) x O— (2) (where x is an integer of 1 to 5). 8. The organic fluorine compound according to claim 7 , wherein the A includes 1 to 50 groups each of which is represented by the general formula (2) in which the x is 1 or 2. 9. The organic fluorine compound according to claim 1 , wherein an average formula weight of the A is in a range of 250 to 6000. 10. The organic fluorine compound according to claim 1 , wherein the organic fluorine compound is a compound selected from the group consisting of a compound that is represented by a chemical formula a compound that is represented by a chemical formula a compound that is represented by a chemical formula a compound that is represented by a chemical formula a compound that is represented by a chemical formula a compound that is represented by a chemical formula or a compound that is represented by a chemical formula said Mn being an approximate average molecular weight, said ca. being circa, and each of said p and q being integers greater than or equal to 1. 11. A lubricant containing the organic fluorine compound according to claim 1 . 12. A processing method of a magnetic recording medium comprising: applying the lubricant according to claim 11 to the magnetic recording medium; and irradiating the lubricant applied to the magnetic recording medium with ultraviolet light.
