The fatty acid includes at least one monovalent linear saturated carboxylic acid. The fatty acid includes a monovalent linear saturated carboxylic acid having a carbon number of at least 14 and no greater than 24 but does not include a monovalent linear saturated carboxylic acid having a carbon number of less than 14 or a monovalent linear saturated carboxylic acid having a carbon number of greater than 24. The fatty acid has a melting point of 60° C. to 80° C. The fatty acid accounts for 5% by mass to 20% by mass of the ester mixture.
