PROBLEM TO BE SOLVED: To provide porous vanadium oxide which is formed into a structure having a stabilized shape even when fired by achieving shape control for obtaining the intended shape, and to provide a method therefor. SOLUTION: The pH of a vanadium-containing solution is adjusted to≤2 to form a wet gel, the wet gel is aged, the aged gel is frozen from one direction and a solvent is removed from the frozen gel to form vanadium oxide of a monolithic structure, which has straight micropores of 5-50μm average pore size and mesopores of 5-25 nm average pore size in a partition wall portion.
