PROBLEM TO BE SOLVED: To solve the problems in which: in an electric dust collector and a flying organism removal device, a conductive base material to which a high voltage is applied is covered with insulating resin to prevent arc discharge, but electric charges accumulate on the surface of an electrode and dust collecting capability and capturing capability deteriorate after a long time use and as a conductor electrode is configured by metal, weight increases in a large-sized product, and it requires a large amount of labor in installation and transportation.SOLUTION: An electrode can be provided which does not generate arc discharge, in which electric charges do not accumulate on the surface of the electrode and in which capturing performance does not deteriorate after a long time use by covering at least one of conductive base materials with a semiconductive layer in which surface resistivity is 108-1011 Ω/sq., and volume resistivity is 108-1011 Ω cm. Also, as a structure for the conductive base material, weight reduction can be achieved while keeping a power feeding property equivalent to that of metal by performing metal plating processing on the surface such as a resin molding product and the like.COPYRIGHT: (C)2014,JPO&INPIT【課題】電気式集塵機や飛動生物除去装置において、高電圧が印加される導電性基材はアーク放電を防ぐために絶縁性の樹脂で被覆されるが、長期間の使用では電極表面に電荷が蓄積し集塵能力や捕捉能力が低下するという課題があった。また、導電体電極が金属で構成されるため大型品になると重量が増加し、取り付けや運搬の際に多大な労力を必要とする問題があった。【解決手段】導電性基材の少なくとも一つを、表面抵抗率が108~1011Ω/□、かつ体積抵抗率が108~1011Ω・cmの半導電層で被覆することでアーク放電を発生させず、電極表面への電荷の蓄積もなく長期の使用で捕捉性能が低下しない電極を提供できる。また、導電性基材の構造として、樹脂成形物などの表面に金属鍍金処理などをすることにより、金属同等の給電性を持ちながら軽量化することが可能となる。【選択図】図1
