考案の効果
(1) 電極球は方向性がない（どちらを向いていて
もよい）ので、電極球埋め込み紐を、押出し機
を使つて作ることができる。したがつて、製造
が容易であり、かつコストが安い。Effects of the invention (1) Since the electrode sphere has no directionality (it can face either way), the electrode sphere embedded string can be made using an extruder. Therefore, manufacturing is easy and cost is low.
(2) 電極が球であるから、エツジのような電界の
集中する部分がなく、したがつて、特性の安定
した接続部が得られる。(2) Since the electrodes are spherical, there are no areas like edges where the electric field concentrates, and therefore a connection with stable characteristics can be obtained.
