Title:
MAGNETIC COUPLING TYPE COIL COMPONENT AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2020013937
Kind Code:
A
Abstract:
To provide a magnetic coupling type coil component in which a coupling coefficient is increased by current applied to a coil conductor.SOLUTION: A magnetic coupling type coil component 1 includes intermediate magnetic layers 19a and 18b, a magnetic base having a first magnetic layer 20a provided on the intermediate magnetic layer 19a and a second magnetic layer 20b provided below the intermediate magnetic layer 18b, a first coil conductor 25a provided in the first magnetic layer 20a, and a second coil conductor 25b provided in the second magnetic layer 20b. The intermediate magnetic layers 19a and 18b have a saturation magnetic flux density lower than the first magnetic layer 20a and the second magnetic layer 20b in a first region 51 in which the first coil conductor 25a and the second coil conductor 25b overlap in plan view.SELECTED DRAWING: Figure 4
