Summary:PROBLEM TO BE SOLVED: To provide lubricant base oil and its composition which achieve a higher traction coefficient and more excellent low-temperature fluidity at high temperature than conventional traction drive oil at a higher level.SOLUTION: Lubricant base oil contains at least one compound being substituted or unsubstituted alicyclic hydrocarbon having a polycyclic structure that the total carbon number is 15-20 and a ratio [tertiary and quaternary carbon number on cyclic skeleton/total carbon number] of a tertiary or quaternary carbon number forming the cyclic skeleton to the total carbon number is 0.5 or more.SELECTED DRAWING: None 【課題】従来のトラクションドライブオイルよりも高温における高いトラクション係数と優れた低温流動性とをより高い次元で両立させた、潤滑油基油及びその組成物を提供する。【解決手段】置換または無置換の、多環構造を有する脂環式炭化水素であり、１５〜２０の総炭素数を有し、環骨格を形成する３級または４級炭素数と、総炭素数との比［環骨格上の３級及び４級炭素数／総炭素数］が０．５以上の構造の化合物を少なくとも１種含む、潤滑油基油。【選択図】なし
