  • Patent number: 11631524
    Abstract: In an exemplary embodiment, a coil component includes: an element body part 10 and a coil 30 of spiral shape constituted by multiple turn units 32 connected in a coil axial direction; wherein each turn unit 32 has, in a cross-sectional view in the width direction of the turn unit 32, a flat side 40 that extends in a second direction substantially perpendicular to the coil axis of the coil 30; and the point of intersection 48 between a figure line 42 corresponding to the longest part in a first direction, and a figure line 44 corresponding to the longest part in the second direction, with respect to the coil axis, is positioned on the figure line 42 within one-quarter of the figure line away from one end 50 on the side 40 or from the other end 52 opposing the side 40.

  • Patent number: 11056269
    Abstract: In an embodiments, a coil component includes: an element body part 10 and a coil 30 of spiral shape constituted by multiple winding conductors 32 and through hole conductors 34 that interconnect the winding conductors 32; wherein each winding conductor 32 has, in a cross-sectional view in the width direction of the winding conductor 32, a flat side 40 that extends in a second direction substantially perpendicular to the coil axis of the coil 30; and the point of intersection 48 between a figure line 42 corresponding to the longest part in a first direction, and a figure line 44 corresponding to the longest part in the second direction, with respect to the coil axis, is positioned on the figure line 42 within one-quarter of the figure line away from one end 50 on the side 40 or from the other end 52 opposing the side 40.
