Title:

INDUCTOR COMPONENT

Document Type and Number:

WIPO Patent Application WO/2022/181178

Kind Code:

A1

Abstract:

An inductor component (10) includes an element (20). In the element (20), plate-shaped magnetic thin strips (40) are layered in a direction orthogonal to a main face (MF) of the magnetic thin strips (40). Inside the element (20), inductor wiring (30) extends along the main face (MF). The axis along which the inductor wiring (30) extends serves as a center axis (CA). In a cross-sectional view orthogonal to the center axis (CA), an axis along the main face (MF) is a first axis (X), and an axis orthogonal to the main face (MF) is a second axis (Z). In the cross-sectional view, from among the magnetic thin strips (40) which are layered with respect to the inductor wiring (30) in a direction along the second axis (Z), those magnetic thin strips (40) of which the distance from the inductor wiring (30) in the direction along the second axis (Z) is shortest serve as first magnetic thin strips (41). When a first virtual line (VL1) is drawn through the first magnetic thin strips (41) in the direction along the first axis (X), the one-dimensional filling factor, with respect to the element (20), of the magnetic thin strips (40) on the first virtual line (VL1) is 90%.
