摘要：PURPOSE:To improve the productivity of a high frequency coil by cutting a part of a film conductor for forming a printed coil to form a cut portion, thereby mechanizing the regulation of the inductance of the coil with a simple structure. CONSTITUTION:A shaded portion 4 is a cut portion of a film conductor 1 cut by a lar trimming unit or a sandblast trimming unit. A cut groove 7 is formed by partly cutting the conductor 1 by the lar or sandblast trimming unit. The inductance of the coil can be incread by designing the initial inductance of the coil 1 smaller than a desired value, mounting necessary parts such as a capacitor 2 and a vari-cap diode 3, and then cutting the conductor 1 by the lar or sandblast trimming unit.
