Embodiment Construction

[0017] Below, an embodiment of the inductor assembly mounting substrate mounting the inductor assembly is described. Further, in order to make the drawings easy to understand, there is a case where the enlargement represents the constituent elements. The size ratio of the constituent elements is sometimes different from the actual situation, or as otherwise in the drawings.

[0018] as Figure 1 As shown, the inductor member mounting substrate 10 has a substrate 20 and an inductor member 30.

[0019] Substrate 20 becomes plate-like. The substrate 20 is configured with a first wiring 21. The terminal portion of the first wiring 21A is exposed on the first side of the thickness direction side of the substrate 20. The portion exposed on the first side of the substrate 20 in the terminal 21A is the first pad 21L. Further, there is a second wiring 22 configured within the substrate 20. The terminal portion of the second wiring 222A is exposed on the first side of the substrate 20. The ...

Abstract

The invention relates to an inductor component and an inductor component mounting substrate. A component main body (40) of an inductor component (30) has a mounting surface (41) and a top surface (42). A spiral inductor wiring (50) that advances in the direction of extension of the winding center axis is provided inside the component main body. A first external electrode (60) is connected to a first end of the inductor wiring (50). A second external electrode (70) is connected to a second end of the inductor wiring (50). The component main body has a first inclined surface (45) that is connected to a first end of a first side of the mounting surface (41) in the longitudinal direction and that is inclined so as to approach the top surface (42) side as the distance from the first end increases. The component main body (40) has a second inclined surface (46) that is connected to a second end on a second side in the longitudinal direction of the mounting surface (41) and that is inclined so as to approach the top surface (42) side as the distance from the second end increases. The winding center axis extends in a direction parallel to the mounting surface (41) and perpendicular to the longitudinal direction.

Description

Technical field [0001] The present disclosure relates to inductor components and inductor components mounting substrates. Background [0002] The part body of the inductor component described in Patent Document 1 has a mounting surface and a top surface with the mounting face. When viewed from a direction perpendicular to the mounting surface, the length of each side of the top surface is larger than the length of each side of the mounting surface. In addition, the top and mounting surfaces are connected by a sloping surface that is inclined relative to the mounting surface. That is, the body of the component becomes a reverse four-sided pyramid table that extends from the mounting surface to the top surface. [0003] Inside the body of the part, the inductor wiring is wound into a vortex. At the first end of the inductor wiring is connected a first external electrode. The first external electrode extends from the mounting surface in the body of the component throughout the incl...
