困難である。 When etching the surface of a synthetic resin with a commonly used organic solvent, it softens due to swelling.
Furthermore, since it dissolves as a highly viscous liquid, it is difficult to perform so-called sharp-cut etching with clear steps.

面状態が得られる。 In contrast, dry etching, such as plasma sputter etching or ion beam etching, which is used in the manufacture of electronic devices, achieves sharp etching, resulting in a surface with a unique optical reflective quality. The state is obtained.
本考案はこれに着目してなされたものであり、
以下図面を参照して説明する。 The present invention was developed with this in mind,
This will be explained below with reference to the drawings.

樹脂膜２が塗布され、その表面２１が研磨されて
いる。用いる樹脂としてはポリウレタンなどの硬
質樹脂が好ましい。この工程における構造は第１
図に示した従来例と同じである。 As shown in FIG. 2a, a synthetic resin film 2 colored by mixing various pigments is applied to the surface of a metal plate 1 such as brass or nickel silver, and the surface 21 is polished. The resin used is preferably a hard resin such as polyurethane. The structure in this process is as follows:
This is the same as the conventional example shown in the figure.
合成樹脂膜２の表面２１には研磨後に金属膜が
被覆され、通常のフオトエツチング法によりパタ
ーン化されて金属マスク３を構成している。 The surface 21 of the synthetic resin film 2 is coated with a metal film after polishing, and is patterned by a normal photo-etching method to form a metal mask 3.
金属マスクの材料としてはNi，Cu，Cr，Ni−
Cr合金、Ni−Ti合金、Au−Cu合金、Au−Ag−
Cu合金などを用い、無電解メツキあるいは真空
蒸着法により0.5〜１ミクロン厚さに被覆する。 The materials for the metal mask are Ni, Cu, Cr, Ni−
Cr alloy, Ni-Ti alloy, Au-Cu alloy, Au-Ag-
A Cu alloy or the like is used to coat the surface to a thickness of 0.5 to 1 micron by electroless plating or vacuum deposition.

脂膜２が選択的にエツチングされる。 Next, as shown in FIG. 2b, an ion beam is irradiated from the direction of arrow 4 to dry-etch the synthetic resin film 2 to the middle layer. Since the etching rate of the synthetic resin film 2 by argon or oxygen gas ions is much higher than the etching rate of the metal mask 3, the synthetic resin film 2 is selectively etched by etching in a relatively short time.
次に金属マスク３を化学的に除去すると、第２
