PURPOSE:To eliminate the adhesion of a a slurry to the blank part of a core material, by providing a projection to the leading end of the roll of a slurry coating jig and positioning the upper end of the surface, which is contacted with a core material, of the roll above the lower surface of a slit. CONSTITUTION:In the coating of a slurry in the manufacturing of a battery electrode plate, a core material 1 is passed through the vat filled with the slurry and drawn up through a slit 8. At this time, from the part contacted with the blank part of the core material, the slurry is scraped by opposed rolls 12 arranged so as to be mutually pressed to the lower surface of the slit 8 by a spring 9. Therefore, even if the slurry penetrated between the lower surface of the slit 8 and the upper surface of the roll 12 is gradually pushed out to the leading end side of the roll 12 during coating work, said slurry is blocked by the projection 16 provided to the leading end of each roll 12 an does not reach the surface of the core material. As a result, the slurry is prevented from again adhering to the blank part.
