Zusammenfassung:	A particle diameter of a raw material to be pulverized can be decreased within a short time period. A vibration mill includes a container having therein a columnar space with a central axis of the columnar space being almost horizontal while the container is held so as to be vibratable in a direction of within a plane that is almost perpendicular to the 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. 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. The integrated value of volumes of the pulverizing media relative to a space volume inside the cylindrical medium in contact with the pulverizing medium is more than 25%.
