摘要： A method of manufacturing an electronic component includes forming a slit (S) in a connecting electrode (2b) located on the surface of a mother substrate (1) such that the slit extends in a direction intersecting a cutting line (A), and cutting the mother substrate along the cutting line while cutting the connecting electrode having the slit. The connecting electrode is thereby reliably exposed on two opposing cut surfaces, and the reliability of external connection of the electronic component is improved.
摘要翻译：一种电子部件的制造方法包括在位于母基板（1）的表面上的连接电极（2b）中形成狭缝（S），使得狭缝在与切割线（A）相交的方向上延伸，切割在切割具有狭缝的连接电极的同时沿着切割线的母基板。因此，连接电极可靠地暴露在两个相对的切割面上，提高了电子部件的外部连接的可靠性。

摘要： A variable inductor device (10) has at least two coils (2,3). The two coils (2,3) are formed on an insulating substrate (1) with an inductance adjusting portion (4) therebetween. The inductance adjusting portion (4) is electrically connected at one end to a tap center electrode (12). The two coils are electrically connected to each other via the inductance adjusting portion. The inductance adjusting portion (4) is grooved (21) and horizontal paths of the inductance adjusting portion are sequentially disconnected one by one by, for example, applying a laser beam. The inductances are thus varied. It is therefore possible to provide a variable inductor device in which the area required for mounting the device on a printed circuit board is decreased and the inductances (2,3) are stably adjusted while keeping them in balance.
