PROBLEM TO BE SOLVED: To reduce the equipment cost and to improve the yield of a magnetic coating material in a magnetic coating material supplying apparatus for supplying the magnetic coating material to a coating apparatus used for forming a coating film for example, in a magnetic tape as a recording medium, an electrode of a battery or the like. SOLUTION: In the supplying apparatus A for dispersing the magnetic coating material pressurized by a pressurizing means by a dispersing means and supplying the coating material to the coating apparatus, a plunger pump, in which the pulsation of the magnetic coating material is eliminated by shifting the phases of a plurality of plungers to keep the discharge quantity constant, is used.
