Abstract: There are provided graphene powder that may be mass-produced with high quality, an apparatus for producing graphene powder, a method for producing graphene powder, and a product using the graphene powder. A jet flow as a high speed jet stream of a liquid or a gas is output from a jet flow output unit, and a raw material containing graphite and the jet flow thus output from the jet flow output unit are made to inflow to an input part of a chamber to cleave graphite, thereby outputting graphene powder in the form of fine particles of graphite from an output part. The graphene powder by the production method is formed simply by cleaving the raw material containing graphite with a jet flow, and thus may suffer no contamination due to the absence of contamination with other substances, and thus graphene having high purity and good quality in the form of fine particles may be obtained.
