【発明の詳細な説明】
（産業上の利用分野）
本発明は、コイルの製作にフォトエツチング方法を利用
し、製作工程の簡単化、多量生産。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention utilizes a photoetching method to manufacture a coil, thereby simplifying the manufacturing process and mass-producing it.
省力化を目的としたコイルの製作方法に関する。This invention relates to a method of manufacturing a coil for the purpose of labor saving.
（従来の技術）
従来のコイルの製作は、フェライトコア材等のボビンの

でなく。(Problems to be Solved by the Invention) In manufacturing the above-mentioned coil, adjusting the number of nine turns to obtain a predetermined inductance value was quite troublesome. In addition, winding does not require time-consuming work, such as fixing the ends of the wire with adhesive to prevent the wire from coming off.

ダクタンス値を正確に確保することが困難であった。Variations in inductance values caused a decline in product yield. Furthermore, it is difficult to accurately wind a coil in a pattern or a fractional number such as a 3A main, and as a result, it is difficult to ensure an accurate inductance value.

２を形成する。(Means for Solving the Problems) In order to solve these drawbacks, the present invention attaches a conductive metal such as copper to the core material by electrolytic plating or the like, and then photo-etches it by photo-etching. The plated portion is formed in the same manner as when the conductive wire is wound to obtain a coil having a predetermined inductance value. Please refer to the drawings below for clarity. Figure 1 is an external view of the coil showing the manufacturing process of the present invention, Figure 2 is an external view of the coil showing the manufacturing process of the present invention.
The figure is a structural diagram showing its cross section. First, the required number of core materials 1 forming the bobbin are placed in an electroplating tank (not shown).
A conductive film 2 of copper or the like is formed around the core material 1 by electrolytic plating.

By processing this using a photo-etching method, unnecessary copper is etched away and the photoresist film is removed to form a single-layer coil. In this case, the unexposed part 4
By adjusting the width, length, etc.
任意のインダクタンス値を有するコイルを作成すること
ができる。Coils can be created with any inductance value.
つぎにコイルの巻数を多く必要とするときはパターン５

体のコーティングを行ない。Next, when you need a large number of turns of the coil, use pattern 5.
Either the zero width is narrowed or the coil pattern 5 is coated with an insulator.
再度上記フォトエツチング方法によりコイルを多層化す
