The present invention relates to a fluorine-containing cyclic compound of formula (5): wherein R2-R4 and R9-R15 are independently a hydrogen atom, a halogen atom, or a C1-C25 straight-chain, branched or cyclic alkyl group, and may contain fluorine atom, oxygen atom, sulfur atom, or nitrogen atom. R10 and R11, R12 and R13, or R14 and R15 may be bonded together to form a ring. In such a case, it is a C1-C25 alkylene group that may contain a hetero atom such as oxygen, sulfur and nitrogen, “a” is 0 or 1, “b” is an integer of 0-2 and “c” is an integer of 0-2.
