(57) [Summary] (With correction) [Solution] The circle-converted diameter of the cross section is from 0.01 to 10,000. μm, and a metal oxide structure having a metal oxide protrusion having a ratio of length to a circle-equivalent diameter of a cross section of 0.1 or more, and volatile or sublimable, and The method for producing a metal oxide structure according to the above, wherein one or more kinds of metal compounds which form an oxide by reacting with the compound are released and sprayed onto a substrate set at a higher temperature than the metal compound. The structure of the present invention can increase the surface area with a small volume, and can be used as an insulator, a conductor, a solid electrolyte, a fluorescent display tube, an EL element, a ceramic capacitor, an actuator, a laser oscillation element, a cold cathode element, Ferroelectric memory, piezoelectric, thermistor, varistor, etc., surface modifier, surface protective agent, antireflective agent, surface modifier for antibacterial, antifouling effect, etc., gas phase, liquid phase or both It can be used as a catalyst in a phase or its carrier. |
