<P>PROBLEM TO BE SOLVED: To provide a method of producing a polytetrafluoroethylene granule, which does not require a solvent and can improve fluidity sufficiently. <P>SOLUTION: The method of producing the polytetrafluoroethylene granule includes: a step of obtaining a sheet S by rolling polytetrafluoroethylene particles R; a step of pressing the sheet S against a porous plate 34 to making the sheet S pass through the holes 34a of the porous plate 34, thereby obtaining a granule G; and a step of tumbling the granule G. <P>COPYRIGHT: (C)2012,JPO&INPIT |
