Claim:
1. A method for manufacturing a pulverized material, wherein the method uses a vibration mill provided with: a container having therein a columnar space with a central axis of the columnar space being disposed so as to be almost horizontal while the container being held so as to be vibratable in a direction of within a plane that is almost perpendicular to the said central axis, a cylindrical medium disposed in the container so as to be vibratable, and a plurality of pulverizing media disposed inside the cylindrical medium so as to be vibratable; in the said vibration mill the ratio of an inner diameter of the cylindrical medium in contact with the pulverizing medium to an outer diameter of the pulverizing medium is 2.1 or more, and the integrated value of volumes of the pulverizing media is more than 25% relative to a space volume inside the cylindrical medium in contact with the pulverizing medium; and the method has a pulverizing treatment process of a raw material to be pulverized by vibrating the container after the said raw material to be pulverized is introduced into the container of the vibration mill.
