PURPOSE: A manufacturing method of a ferrite sheet is provided to simplify manufacturing processes for reducing manufacturing costs, to improve productivity, and to reduce failure rate. CONSTITUTION: A manufacturing method of a ferrite sheet (2) for shielding electromagnetic waves comprises the following steps: a sheet formation step (100) forming ferrite sheet molding products (1); and a sintering step (200) laminating the ferrite sheet molding products and sintering the laminated products. In the sintering step, separator sheets (3) are inserted among the ferrite sheet molding products by turns. The sintering step uses a surface-processed metal sheet with the rough contacting surface with the ferrite sheet molding products as the separator sheets.
