ABSTRACT:
This invention intends to provide a coating device capable of forming, in a good work efficiency, a magnetic layer whose surface is free from irregularities in thickness and is flat. The above object is achieved by providing a device wherein a magnetic paint 3A is coated through an extrusion die 1, and, downstream of the die and close to the non-coated side of a substrate 19, a magnetic field generator 12A with a laminated structure composed of plate-like magnets 15 packed in layers is placed inclined by 45.degree.-85.degree. with respect to the running direction R of the substrate. Through this arrangement, the coated surface of magnetic layer 3 will be free from thickness irregularities and be flattened.
