  • Publication number: 20210280360
    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%.
