Disclosed is lubricant base oil that is excellent in lubricity, sludge solubility, low viscosity, and low temperature characteristics and capable of realizing low volatility. The lubricant base oil contains as its main component a diester or triester synthesized from a divalent or trivalent carboxylic acid of 9 or less carbon atoms and a monovalent glycol ether such as an alkylene glycol monoalkyl ether of 3 to 25 carbon atoms and is useful as base oil for lubricating oil and grease. Di(hexyloxyethyl) adipate may be cited as an appropriate example of the diester.
