PROBLEM TO BE SOLVED: To reduce the number of drawing and developing processes by using film reduction of a resist pattern, as well as to improve uniformity within a film plane in a film reduction rate of a resist pattern between sparse and dense pattern regions.SOLUTION: A method for manufacturing a photomask is provided, including steps of: forming a first resist pattern covering a region for forming a light-shielding portion and a region for forming a translucent portion, in which the thickness of the resist film in the region for forming a translucent portion is smaller than the thickness of the resist film in the region for forming a light-shielding portion; and reducing the film in the first resist pattern by excessively supplying ozone to the first resist pattern. Ozone is supplied in such a manner that the supply amount of active oxygen per unit area supplied to the first resist pattern is greater than the consumed amount of active oxygen per unit area consumed by the film reduction in the first resist pattern.
