Title:
COIL COMPONENT, AND SUBSTRATE WITH INTEGRATED COIL
Document Type and Number:
WIPO Patent Application WO/2022/024914
Kind Code:
A1
Abstract:
This coil component comprises a primary winding that generates a magnetic field using input current from the outside, and a secondary winding in which flows an induction current that is generated by the magnetic field. The primary winding includes a plurality of primary-side first circumference parts and a plurality of primary-side second circumference parts, each of which has an annular shape as seen from a first direction. The secondary winding includes a plurality of secondary-side first circumference parts and a plurality of secondary-side second circumference parts, each of which has an annular shape as seen from the first direction. The plurality of primary-side first circumference parts and the plurality of secondary-side first circumference parts are arranged alternating in the first direction and constitute a first tubular part. The plurality of primary-side second circumference parts and the plurality of secondary-side second circumference parts are arranged alternating in the first direction and constitute a second tubular part. The second tubular part is positioned inward of the first tubular part as seen from the first direction. The orientation of the input current flowing to each of the plurality of primary-side first circumference parts, and the orientation of the input current flowing to each of the plurality of primary-side second circumference parts, are the same.
