Document Type and Number:
WIPO Patent Application WO/2024/053620
Kind Code:
A1
Abstract:
This coil component (10) comprises: a first planar coil (11) including a plurality of turn parts (11n), and protrusion pieces (11T) that extend from the inner peripheral edge and/or outer peripheral edge of at least one turn part (11n) among the plurality of turn parts (11n), and that bend so as to separate from the turn part (11n); and a first holding member (20) that overlaps the first planar coil (11) in a state of contacting the plurality of turn parts (11n) of the first planar coil (11). The first holding member (20) includes grooves (22) in a first surface (20A) on which the first planar coil 11 is overlapped, and the protrusion pieces (11T) contact the inner surface of the grooves (22) in the radial direction.
