According to an embodiment of the present invention, an active material coating device coats an active material on a current collector, and comprises: a supply pipe supplying the active material; a manifold connected with the supply pipe and having a form in which the supply pipe is enlarged to the vertical direction with the enlarged direction; a plurality of coaters located on the current collector and arranged to have regular distance each other along the parallel direction with the enlarged direction of the manifold; and a plurality of connection pipes respectively connecting the manifold and a plurality of coaters. According to the present invention, as flux difference in which the active material is transferred from the supply pipe to each coater is minimized, coating is uniformly done. Accordingly, quality of an electrode plate is improved. Electrode plates having different thickness of the coated active material can be manufactured all together by controlling the width of the connection pipe and flux difference of the active material which flows through each coater. |
