    摘要: The purpose of the present invention is to provide: a functional material which is prepared by using aluminum as a base material and has a bactericidal effect; and a method for producing the functional material. The functional material comprises an aluminum base material and a functional film which is a hydrated aluminum oxide film formed on the surface of the aluminum base material. The functional film has nano-order depressions and protrusions formed on the surface thereof and, as a result, the functional film can have a bactericidal effect to kill bacteria. The functional material is produced by subjecting an aluminum base material to a boiling treatment in boiled water for a predetermined treatment time to form, on the surface of the aluminum base material, a hydrated aluminum oxide film having nano-order depressions and protrusions formed on the surface thereof.
