LAMINATION TYPE COIL COMPONENT
Document Type and Number:
Japanese Patent JP2022191427
Kind Code:
A
Abstract:
To provide a lamination type coil component having a large impedance in a high frequency band and excellent in high frequency characteristic.SOLUTION: A lamination type coil component comprises: a lamination body 10 in which a plurality of insulation layers 31a to 31h, and 35a1 to 35b4 are laminated in a longitudinal direction, and which has a coil built therein; and a first external electrode and a second external electrode electrically connected to the coil. A coil 3 is formed by electrically connecting a plurality of coil conductors 32a to 32h laminated in the longitudinal direction with the insulation layers. The coil conductors include: line parts 36a to 36h; and land parts 37a to 37h arranged at end parts of the line parts. The land parts of the coil conductors adjacent in the lamination direction are connected to each other through via conductors 33a to 33q, and in plan view from the lamination direction, are not positioned inside inner peripheral edges of the line parts, and partially overlap the line parts. The diameter of the land part in plan view from the lamination direction is 1.05 times or more and 1.3 times or less of a line width of the line part.SELECTED DRAWING: Figure 9
