（産業上の利用分野）
本発明は導電膜アンテナを備えた自動車用プラスチック
製外装部品およびその製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a plastic exterior part for an automobile equipped with a conductive film antenna and a method for manufacturing the same.
（従来の技術）
最近の自動車には、カーステレオ，テレビ，カーテレホ
ン等多数の電気機器の搭載が急増しており、それに伴な
って、アンテナの役割りも多様化している。(Prior Art) Recently, automobiles are rapidly being equipped with a large number of electrical devices such as car stereos, televisions, and car telephones, and the roles of antennas have also become more diverse.
従来から自動車に取付けられるカーアンテナとしては、
大別して、第４図に示したような引出可能なポールアン
テナ１や、第５図に示したように通常、リアウインド２
の上部に配設される導電膜アンテナ３がある。Car antennas traditionally installed on cars include:
Broadly speaking, they can be divided into a retractable pole antenna 1 as shown in Figure 4, and a rear window antenna 2 as shown in Figure 5.
There is a conductive film antenna 3 disposed on top of the antenna.
これらカーアンテナのうち、導電膜アンテナは次のよう

い例えばアルミ箔を貼着したりして取付けられる。この
場合、導電膜アンテナが配設された個所は一般に不透明
になる。Among these car antennas, the conductive film antenna is arranged in the rear window as follows. In other words, conductive paint is applied in a desired pattern to the upper outer surface or upper inner surface of the rear window, or metal powder is hot-stamped in a desired pattern, or thin, for example, aluminum foil is coated with a desired pattern. It can be attached by pasting. In this case, the location where the conductive film antenna is provided generally becomes opaque.

電膜アンテナの配設位置は制限を受け、また導電膜アン
テナの面積をあまり広くすることができない。(Problem to be Solved by the Invention) However, when an opaque conductive film antenna is disposed in the rear window, it is necessary to prevent the passenger's view from being obstructed by it. Therefore, the placement position of the conductive film antenna is limited, and the area of the conductive film antenna cannot be increased very much.
導電膜アンテナは上記したような制限を受けるため、高
感度用のアンテナの機能は不可避的に不足する。Since conductive film antennas are subject to the above-mentioned limitations, the functions of high-sensitivity antennas are inevitably insufficient.
また、カーアンテナは車戦機器に対応して各種の電波を

、しかし、リャウインドのみではその要求を満たすには
不充分である。In addition, considering that car antennas must be able to receive various types of radio waves in response to vehicle warfare equipment, and must also be able to receive radio waves reliably even when driving with frequent changes of direction, this conductive film antenna is highly recommended. It is preferable to attach as many as possible and over a wide area to the vehicle body, but the rear window alone is not sufficient to meet this requirement.

形されている。Incidentally, in recent automobiles, various exterior parts such as spoilers, sunroofs, trunk lids, etc. are made of plastic in order to reduce weight and thereby reduce fuel consumption. These plastic exterior parts are molded using a mold having a mold surface of a predetermined shape.
そこで、本発明者は、これらの外装部品に導電膜アンテ

を製造するための方法を開発するに至った。Therefore, the inventor of the present invention has proposed that if a conductive film antenna is integrally attached to these exterior parts and the exterior parts are attached to a predetermined location of the automobile, the antenna will not obstruct the view as would be the case if it was attached to the rear window. With the aim of achieving the desired functionality, we have conducted extensive research into the integration of conductive film antennas and exterior parts, leading to the development of the exterior part of the present invention and a method for manufacturing the same.

なる。(Function) The pattern of the conductive film antenna is printed or embedded on the surface of the plastic film. Therefore, if this plastic film is set in a mold whose mold surface is the molding surface of the exterior component, and the plastic for the exterior component is injected into this mold, the above-mentioned plastic film will also be integrated into the molded exterior component. It will be shaped into

うになる。Then, when this exterior part is attached to a predetermined attachment point on the automobile, the conductive film antenna is attached to the automobile. Unlike the case where the antenna is installed in the rear window, there is no need to worry about obstructing the view, so the area of the conductive film antenna can be increased, and a highly sensitive function can be realized.
