Disclosed is a method for producing a fatty acid alkyl ester, which enables production of a fatty acid alkyl ester with high yield without using an alkali metal catalyst.  A catalyst for production of a fatty acid alkyl ester is also disclosed.  The method for producing a fatty acid alkyl ester is characterized in that a fatty acid alkyl ester is produced by reacting a triglyceride with an alkyl carbonate or an alcohol in the presence of an organic base carbonate.  The catalyst for production of a fatty acid alkyl ester is characterized by being mainly composed of an organic base carbonate. La présente invention a pour objet un procédé de production d'un ester alkylique d'acide gras qui permet sa production avec un rendement élevé à l'aide d'un catalyseur de métal alcalin. L'invention concerne également un catalyseur pour la production d'un ester alkylique d'acide gras. Le procédé de production d'un ester alkylique d'acide gras est caractérisé en ce qu'un ester alkylique d'acide gras est produit en faisant réagir un triglycéride avec un carbonate d'alkyle ou un alcool en présence d'une base organique carbonate. Le catalyseur pour la production d'un ester alkylique d'acide gras est caractérisé en ce qu'il est principalement composé d'une base organique carbonate.
