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):
wherein 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 is
wherein R represents C
1-3
alkyl, and n represents 0, 1, or 2; when n represents 2, R may be the same or different.
