Patent ID: 8329087

Claim:
A method of manufacturing a magnetic sheet, the method comprising: a slurry sheet forming step of forming slurry by mixing flat soft magnetic metal powder in a binding material, and forming a slurry sheet by shaping the slurry into a sheet; a local magnetic field applying step of unifying only the orientation of the flat soft magnetic metal powder, which exists in the partial area, of the entire flat soft magnetic metal powder mixed in the slurry sheet in a predetermined direction by locally applying a magnetic field to a partial area of the expanded slurry sheet in a predetermined direction; and a slurry curing step of forming a magnetic sheet by curing the slurry sheet after the local magnetic field applying step; an entire magnetic field applying step of unifying only the orientation of the entire flat soft magnetic metal powder, which is mixed in the slurry sheet, in a predetermined direction by applying a magnetic field to the entire area of the expanded slurry sheet in a predetermined direction after the slurry sheet forming step and before the local magnetic field applying step.
