A pattern formation method includes: forming a photosensitive hard mask made of a transition metal oxide film on a surface of a substrate; exposing the photosensitive hard mask to EUV light in a desired pattern; causing a state change in an exposed region by heat generated during exposure; and selectively removing either a region where the state change has occurred or a region where the state change has not occurred.
