Laminated sheet type ferrite bead and manufacturing method thereof

The invention discloses a laminated sheet type ferrite bead and a manufacturing method thereof. The method comprises the following steps: respectively manufacturing a ferrite raw ceramic chip and a non-magnetic intermediate interlayer raw ceramic chip from a ferrite material and a non-magnetic intermediate interlayer material; perforating the ferrite raw ceramic chip and the middle interlayer rawceramic chip; arranging an inner electrode coil and upper and lower leading-out parts in the perforated ferrite raw ceramic chip and a perforated middle interlayer raw ceramic chip; filling the ferrite raw ceramic chip and the middle interlayer raw ceramic chip which are provided with the inner electrode coils and the upper and lower leading-out parts with ferrite to obtain a filled ferrite raw ceramic chip and a filled middle interlayer raw ceramic chip; laminating the filled ferrite raw ceramic chip and the filled interlayer raw ceramic chip to obtain a blank block; forming the blank block into a single laminated sh
