Embodiment Construction

[0028] Below, according to Figure 1 to Figure 14 One embodiment of an inductor component and a method of manufacturing the inductor component will be described. In addition, in the drawings, constituent elements are sometimes shown enlarged for easy understanding. Dimensional ratios of components may differ from actual ones, or may differ from contents in other drawings. In addition, hatching is given in a cross-sectional view, but the hatching of some components may be omitted for easy understanding.

[0029]

[0030] like figure 1 As shown, the inductance component 10 has a body 20 made of a magnetic material. That is, the body 20 has magnetism. For example, the body 20 is composed of a resin containing metal magnetic powder. Examples of the metal magnetic powder include iron, nickel, chromium, copper, aluminum, and alloys thereof. Moreover, resin materials, such as epoxy resin, are mentioned as resin containing metal magnetic powder. In consideration of insulation...

Abstract

The invention provides an inductor component and a method for manufacturing inductor components, which can prevent the deviation of inductor wiring position from the designed position inside the component. The inductor component includes an element body having magnetism, a resin layer provided inside the element body, and inductor wirings provided inside the element body and having a contact surface that is in contact with the resin layer. A configuration ratio of the inductor wirings is equal to or less than about "0.9". In a transverse plane of the inductor wirings perpendicular to an extending direction of the inductor wirings, in a case where a largest dimension among dimensions in a height direction perpendicular to the contact surface is defined as a maximum dimension, the configuration ratio is a ratio of the largest dimension to a dimension of the contact surface in the transverse plane.

Description

technical field [0001] The present invention relates to an inductance component and a method for manufacturing the inductance component. Background technique [0002] Patent Document 1 describes an example of an inductance component in which wiring is provided inside a magnetic main body. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2016-6830 [0004] In an inductance component in which wiring is provided inside the main body as described above, the position of the wiring may deviate from the designed position. The design position is the position of the wiring determined by the design. If the position of the wiring inside the main body deviates from the set position in this way, the performance of the inductance component may change. Therefore, the deviation between the position of the wiring and the designed position is suppressed. Contents of the invention [0005] An inductor component for solving the above-mentioned problems includes: a main body havin...
