コイル部品
Document Type and Number:
Japanese Patent JP6996276
Kind Code:
B2
Abstract:
To reduce the number of insulating substrates required while preventing contact between coil portions adjacent in the stacking direction.SOLUTION: A coil component includes a coil portion 100 formed on the surface 11 of an insulating substrate 10, a coil portion 200 formed on the surface 12 of the insulating substrate 10, a coil portion 300 formed on the surface 24 of an insulating substrate 20, a coil portion 400 formed on the surface 36 of an insulating substrate 30, connection patterns P11 to P16 formed on the surface 23 of the insulating substrate 20, and connection patterns P21 to P26 formed on the surface 35 of the insulating substrate 30. The inner peripheral end of coil portion 100 and the inner peripheral end of coil portion 200 are connected to each other through connection portions TH11 to TH16 provided so as to penetrate through the insulating substrate 10, and the connection patterns P11 to P16 and the connection patterns P21 to P26 are connected to each other through an opening 10a provided in the insulating substrate 10. Thus, the number of insulating substrates required can be reduced while contact between the coil portions is prevented.SELECTED DRAWING: Figure 1
