  An object of the present invention is to provide a novel method for producing a steroid compound. The present invention provides a method for producing 3,7-dioxo-5β-cholanic acid or ester derivatives thereof, which uses, as raw materials, sterols having double bonds at positions 5 and 24, such as cholesta-5,7,24-trien-3β-ol, ergosta-5,7,24(28)-trien-3β-ol, desmosterol, fucosterol, or ergosta-5,24(28)-dien-3β-ol, and which comprises the following 4 steps: (I) a step of performing oxidation of a hydroxyl group at position 3 and isomerization of a double bond at position 5 to position 4; (II) a step of converting position 24 to a carboxyl group or an ester derivative thereof by the oxidative cleavage of a side chain; (III) a step of introducing an oxygen functional group into position 7; and (IV) a step of constructing a 5β-configuration by reduction of a double bond at position 4.
