According to one aspect of the present invention, an organic fluorine compound is represented by a general formula

(R--E-CH.sub.2).sub.2-A(1A)

(where A is a divalent perfluoropolyether group, 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

OCH.sub.2CH(OH)CH.sub.2O

two groups each of which is represented by a general formula

R--E-CH.sub.2

may be the same or different, and at least one n among two is an arylene group).

A lubricant composition includes a base oil and melamine cyanurate. The base oil includes a perfluoropolyether oil having a straight chain structure. The lubricant composition is for one of a resin-resin sliding section and a resin-metal sliding section. A melamine cyanurate content is within a range of 1-20% by mass with respect to a sum of the base oil and melamine cyanurate.
