A method in which various kinds of powdered or granular materials such as metal, ceramic and the like are put into a metal cylindrical container which can be plastically-deformed, or in the space between a container and a core or a substrate, the surroundings are sealed so that the powdered or granular materials do not leak out, the container is locally pressed by a small roller, and the locally pressed treatment is provided to the whole container region. Therefore, the internal powdered or granular materials are pressurized to a uniform density without regard to selective parts, and the materials are formed to various shapes by means of the local pressing.
