A method of manufacturing a magnetic sheet includes a slurry sheet forming step, a local magnetic field applying step, and a slurry curing step. In the slurry sheet forming step, slurry is formed by mixing flat soft magnetic metal powder in a binding material, and a slurry sheet is formed by shaping the slurry into a sheet. In the local magnetic field applying step, 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 is unified in a predetermined direction by locally applying a magnetic field to a partial area of the expanded slurry sheet in a predetermined direction. In the slurry curing step, a magnetic sheet is formed by curing the slurry sheet after the local magnetic field applying step.
