An object of the present invention is to provide a lubricant base oil for power transmission (in particular, a lubricant base oil for traction drives) having a high traction coefficient and a high flash point. The present invention relates to a lubricant base oil for power transmission comprising an alicyclic dicarboxylic acid diester compound represented by general formula (1): n nwherein R 1 to R 5 are the same or different, and each represents hydrogen or linear or branched C 1-4 alkyl, and two R 1 , two R 2 , two R 3 , two R 4 , and two R 5 may respectively be the same or different; and ring A isn n nwherein R represents C 1-3 alkyl, and n represents 0, 1, or 2; when n represents 2, R may be the same or different. |
