LC-included electronic component

摘要

An LC-included electronic component has a greatly reduced size, a greatly increased resonator Q, and outstanding reliability. Inductor via holes 2 &cir& are successively connected in a direction (Z) in which insulating sheets (42-48) are stacked to define columnar inductors (L1,L2,L3). The inductor via holes 2 &cir& each have a Y-direction dimension greater than an X-direction dimension on the X-Y plane of a section shape, and the shape has Y-direction ends of increased width. Specifically, each Y-direction end of the inductor via holes 2 &cir& is substantially circular, and the other portions are linear.
