To effectively suppress the production of peroxides and simply, economically and advantageously produce an ester by reacting an acid with an alcohol in at least an atmosphere under a reduced pressure or a vacuum or an inert gas atmosphere in the whole production process.

An acid (e.g. a monocarboxylic acid, a dicarboxylic acid, a polyvalent carboxylic acid or a carboxylic acid anhydride) is reacted with an alcohol (e.g. a monoalcohol, a polyhydric alcohol or glycols) in at least an atmosphere under a reduced pressure or a vacuum or an atmosphere of an inert gas (e.g. nitrogen gas as a preferred one) in the whole production process (an esterifying reactional step, a neutralizing step, a water washing step, a dehydrating step, a filtering step, a drying step, a distilling step, etc.), at about 50-300°C preferably by using a catalyst.
