材の混合量が制限され塗料の場合と同様に高密度な導電
性充填材層が得られない。However, with paints mixed with conductive fillers, the amount of conductive filler mixed is limited due to painting workability, and a high-density conductive filler layer cannot be obtained.Plastic plates mixed with conductive fillers In this case, the amount of conductive filler mixed is limited due to moldability and mechanical properties, and a high-density conductive filler layer cannot be obtained as in the case of paint.
本発明は上記従来の問題点を解決する手段として基材表

本発明の作用は下記の通りである。 The effects of the present invention are as follows.
基材表面に接着剤を介して導電性小体を電着すると非常
に密なる導電性不休電着層が得られる。When conductive particles are electrodeposited on the surface of a substrate via an adhesive, a very dense conductive non-dead electrodeposited layer can be obtained.
該電着層において導電性小体は接着剤層に強固に食い込
んでいる。In the electrodeposited layer, the conductive particles firmly bite into the adhesive layer.
したがって本発明においては機械的強度が大きくかつ電
磁波遮蔽性の極めて優れた材料を得ることが出来る。Therefore, in the present invention, it is possible to obtain a material that has high mechanical strength and extremely excellent electromagnetic wave shielding properties.
