Provided are a catalyst for producing a fatty acid alkyl ester, which has more excellent yield and activity stability than those of conventional ones, a method for producing the catalyst, and a method for producing a fatty acid alkyl ester using the catalyst. The catalyst contains an alumina-containing porous carrier, and at least two elements carried by the carrier and selected from group 6 of the periodic table, wherein the catalyst has an average pore diameter of 9.5-27 nm, a total pore volume of 0.5-1.0 ml/g, and a specific surface area of 120-300 m2/g. A proportion of the volume of pores having a diameter which is the average pore diameter ± 1.5 nm to the total pore volume is 15-70%, and a proportion of the volume of pores having a diameter which is the average pore diameter ± 5 nm to the total pore volume is 60% or more. |
