  • Patent number: 4574262
    Abstract: A lamination of a resilient and elongate magnetic sheet and a conductor strip is rolled up around a magnetic winding core to form a roll, and then the roll is sintered to produce an intermediate product. The conductor strip has both ends at both sides of the magnetic sheet so that both ends of the conductor strip are respectively exposed at both sides of the roll. Terminal electrodes are respectively attached to the both sides of the intermediate product to complete the chip coil. Another magnetic sheet may be provided to make the thickness of the lamination substantially uniform throughout the entire area. A second conductor strip may be provided in the lamination so that a coil having a tap can be actualized. The shrinkages of the winding core and the magnetic sheet are selected so that a desirable sintered product will result without suffering from delamination or cracks.
