The invention provides a method for producing a chiral transition metal oxide structure in a simpler manner; and a chiral transition metal oxide structure produced by the method. The method for producing a chiral metal oxide structure is employed, said method comprising: a sol-gel step of forming a metal oxide layer on the surface of a chiral supermolecule crystal of an acid-base-type complex by a sol-gel method, wherein the acid-base-type complex comprises a polymer having a linear polyethylene imine backbone and a chiral dicarboxylic acid compound having two carboxyl groups and also having 4 or more carbon atoms and the sol-gel method comprises reacting the chiral supermolecule crystal with a transition metal compound having a chelating ligand that is at least bidentate; and a firing step of firing the chiral supermolecule crystal that has been subjected to the sol-gel step to thermally decompose the chiral supermolecule crystal that is an organic substance, thereby producing a transition metal oxide structure that is formed from the metal oxide layer using the supermolecule crystal as a template.
