Abstract
In an exemplary embodiment, a passive component which is a surface mounting component, includes: a substrate body 10 having insulation property; an internal conductor 50 embedded in the substrate body 10; and an external electrode 70 provided on the bottom face 12, which is the mounting surface, of the substrate body 10 and electrically connected to the internal conductor 50; wherein the external electrode 70 has a face 86 roughly parallel with the bottom face 12 of the substrate body 10, and a dome-shaped projection 80 that bulges, with reference to the roughly parallel face 86, away from the bottom face 12 of the substrate body 10. The passive component can prevent misalignment problems at mounting.
Claims10
A passive component being a surface mounting component, comprising:
- a substrate body having insulation property;
- an internal conductor embedded in the substrate body, the internal conductor including a coil conductor;
- and an external electrode provided on a mounting surface of the substrate body and electrically connected to the internal conductor;
- wherein the external electrode has a planar principal face substantially parallel with the mounting surface of the substrate body, and a dome-shaped projection that bulges in an outward direction from the planar principal face away from the mounting surface of the substrate body, and wherein the internal conductor has a lead conductor contacting and extending parallel to an axis of the coil conductor, inside the substrate body, from an end part of the internal conductor in the outward direction out to the mounting surface of the substrate body and connected to the external electrode, an end part of the lead conductor projects from the mounting surface of the substrate body, and the projection is formed as a result of the external electrode covering the end part of the lead conductor.
