A stirring apparatus for increasing processing speed and preventing deterioration of processing quality, includes a vessel having a predetermined number of liquid supply ports into which liquid to be stirred is made to flow; a liquid exhaust port from which liquid is discharged after stirring; stirring impellers separately arranged at two positions opposed to each other in the vessel, the stirring impellers being rotated in directions opposite to each other such that the liquid in the vessel is stirred; external magnets arranged outside the walls of the vessel close to the stirring impellers, the external magnets having magnetic couplings having no shafts which penetrate the vessel and connect with the stirring impellers; and external motors arranged outside the vessel, for driving the external magnets such that the magnets rotate the stirring impellers.
