    摘要: An ester wax of the present invention is obtained by a condensation reaction of carboxylic acid and alcohol; wherein the carboxylic acid contains a single kind of saturated linear monocarboxylic acid having 14 to 30 carbon atoms as a main component, and the single kind of carboxylic acid makes up 60 wt% or more of the entire carboxylic acid; the alcohol contains a single kind of saturated linear monohydric alcohol having 14 to 30 carbon atoms or a single kind of polyhydric alcohol having 2 to 6 hydroxyl groups and having 2 to 30 carbon atoms as a main component, and when the monohydric alcohol is the main component, the monohydric alcohol makes up 60 wt% or more of the entire alcohol and when the polyhydric alcohol is the main component, the polyhydric alcohol makes up 80% or more of the entire alcohol; and the ester wax has an acid value of 3mgKOH/g or less, and a hydroxyl value of 5mgKOH/g or less, and a maximum peak temperature in a differential thermal curve is in a range from 55 DEG C to 90 DEG C.
