Title:
METHOD FOR MANUFACTURING COIL COMPONENT AND COIL COMPONENT
Document Type and Number:
Japanese Patent JP2017011185
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a coil component capable of preventing layer separation due to a thermal stress.SOLUTION: A method for manufacturing a coil component comprises the steps of: bonding a dummy metal layer onto one surface of a base; laminating a base insulation resin 30 on the dummy metal layer; forming a coil substrate by covering a first spiral wiring 21 with a first insulation resin 31 by laminating the first spiral wiring 21 and the first insulation resin 31 in this order on the base insulation resin 30 and covering a second spiral wiring 22 with a second insulation resin 32 by laminating the second spiral wiring 22 and the second insulation resin 32 in this order on the first insulation resin 31; peeling the base from the dummy metal layer on an adhesion surface between one surface of the base and the dummy metal layer; removing the dummy metal layer from the coil substrate; and covering the coil substrate with a magnetic resin 40.SELECTED DRAWING: Figure 2
