Zusammenfassung:	PROBLEM TO BE SOLVED: To provide base oil for lubricant oil, which restrains viscosity of the base oil from being high, which is excellent in low evaporation property under high temperature environment, and which has flow property that makes it usable over a wide temperature range from low temperature to high temperature, and lubricant oil.SOLUTION: Lubricant base oil is diester compounds of a formula (1) or specific diester compounds. (Ris a monovalent group of a total carbon number from 8 to 16, having at least one ether bond, and straight/branched saturated hydrocarbon chain; n is an integer from 5 to 11.)SELECTED DRAWING: None 【課題】高粘度化が抑制され、かつ高温環境下での低蒸発性に優れ、低温から高温までの広い温度範囲で使用可能な流動性を有する潤滑油用基油及び潤滑油の提供。【解決手段】潤滑油用基油は、式（１）又は特定のジエステル化合物。（Ｒ１は少なくとも１つのエーテル結合と直鎖／分岐鎖の飽和炭化水素鎖とを有する総炭素数８〜１６の１価の基；ｎは５〜１１の整数）【選択図】なし
