  • Patent number: 11942262
    Abstract: In an inductor component, an inductor wire is in an element body and extends on a virtual flat plane passing inside the element body. A wire main body of the inductor wire has an oblong rectangular shape elongated in a length direction in the top view, and thus, a wire width perpendicular to the extending direction is constant. From each edge of the wire main body in a width direction, protrusions having an oblong rectangular shape in the top view protrude and extend, from a center of the wire main body in the extending direction of the wire main body, in a direction perpendicular to the extending direction, on both sides in the width direction of the wire main body, with the extending direction sandwiched between the protrusions. An area ratio of a protrusion area of the protrusions to an area of the wire main body is within 7.2%.

    Abstract: In an inductor component, an inductor wiring is provided inside an element body. The inductor wiring includes a wiring main body and a skirt portion adjacent to the wiring main body in a height direction of the inductor wiring. A dimension in a height direction in the wiring main body is larger than a dimension in the height direction in the skirt portion. A dimension of the skirt portion in a width direction in the inductor wiring increases as a distance from the wiring main body in the height direction increases. A dimension in the width direction of a distal end of the skirt portion is larger than a dimension in the width direction of the wiring main body.

  • Publication number: 20230039428
    Abstract: A magnetic material includes magnetic particles. When a magnetic particle is rotated by 360/n degrees (n is an any integer equal to or greater than 2) around a gravity center position of the particle in a planar region, an area of the particle after the rotation overlaps with an area of the particle before the rotation by 90% or more. In the planar region, gravity center positions of from nine to eleven particles are present on a band portion in a rectangular shape. For the particles in the planar region, when a number-based 50% cumulative frequency distribution of maximum lengths in a direction passing through respective gravity center positions is defined as ?, a 10% cumulative frequency distribution is equal to or greater than 0.9?, and a 90% cumulative frequency distribution is equal to or less than 1.1?. A surface of the particle is covered with an insulating film.
