Abstract: One object is to compensate the reduction of the Q value due to reduction of core sectional area of a coil of an inductor, and the reduction of positional accuracy and adhesive strength of components mounted on a printed circuit board due to reduction of area of external electrodes, both caused by downsizing of component sizes. An inductor is provided which includes: a coil formed in an insulator and having one end and the other end thereof formed in a direction away from a mounting surface; and lead-out portions connected to the coil at positions more distant from the mounting surface than a portion of the coil closest to the mounting surface.
Abstract translation: 一个目的是为了补偿由于电感器线圈的芯截面积的减小引起的Q值的降低，以及由于外部电极的面积的减小而安装在印刷电路板上的部件的位置精度和粘合强度的降低 都是由于组件尺寸的缩小造成的。 提供一种电感器，其包括：形成在绝缘体中的线圈，并且其一端和另一端沿远离安装表面的方向形成; 以及与最靠近安装表面的线圈的一部分相比，在与安装表面更远的位置连接到线圈的引出部分。
