    • A method of fabricating a composite ferrite sheet including the steps of: (a) forming a grooved green ferrite sheet having a non-intersecting grid pattern by pressing a groove forming die including a plurality of first protrusions and a plurality of second protrusions having a triangular cross sectional shape, each protrusion of at least one of the plurality of first protrusions and the plurality of second protrusions being discontinuous at each imaginary intersecting portion at which extension lines of the respective first and second protrusions intersect each other, (b) firing the grooved ferrite green sheet to obtain a sintered ferrite sheet, (c) bonding at least one supporting sheet to at least one of opposite major surfaces of the sintered ferrite sheet, and (d) rupturing the sintered ferrite sheet along the grooves into a multiplicity of separate and independent rectangular planar ferrite segments which are bonded to the supporting sheet.
