Title:
COIL COMPONENT
Document Type and Number:
Japanese Patent JP2021027080
Kind Code:
A
Abstract:
To provide a coil component in which a gap portion can be easily formed.SOLUTION: A coil component includes an element assembly 10 and a coil provided inside the element assembly. The element assembly 10 includes a plurality of first magnetic layers 11 and a plurality of second magnetic layers 12 which are laminated. The coil includes a plurality of laminated coil conductor layers 21. The coil conductor layer 21 is sandwiched between the first magnetic layer 11 and the second magnetic layer 12. The pore area ratio of the second magnetic layer 12 is smaller than the pore area ratio of the first magnetic layer 11, and a gap portion 51 exists between the second magnetic layer 12 and the coil conductor layer 21.SELECTED DRAWING: Figure 4
