Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing biodiesel fuel oil reducible of carbon residue of a 10% residual oil in the biodiesel fuel oil.SOLUTION: In the method for producing biodiesel fuel oil by a transesterification reaction between alcohol and raw material oil and fat: a transesterification reaction process and a step of performing layer separation of a reaction liquid are carried out in this order; and then, a step of bringing an obtained light liquid into contact with an adsorbent and a step of bringing the light liquid into contact with a cation exchange resin are carried out. In particular, a step of removing or reducing an alcohol content in the light liquid is carried out before bringing the light liquid into contact with the cation exchange resin.
