Abstract
In an exemplary embodiment, a passive component, which is a surface mounting component, includes: a substrate body having insulating property; an internal conductor built into the substrate body; and an external electrode provided on a mounting face of the substrate body and electrically connected to the internal conductor; wherein the external electrode has a face parallel with the mounting face of the substrate body, and a concaved part which is concaved with reference to the parallel face toward the mounting face side of the substrate body and whose shape at the parallel face is circular or oval. The passive component can prevent its joining strength with a circuit board from decreasing, while preventing the component size from increasing.
