A semielectric conductive waterproofing mixture is composed of 100 wt. parts liquid resin, 10-100 wt. parts conductive carbon black, 1- 20 wt. parts flow- preventing agent, 0-30 wt. parts inorganic filler, 0-10 wt. parts heat-stubilizer and 0-30 wt. parts mineral oil. The liquid resin having a viscosity of 1000 poise or more (30 deg.C) is pref. silicon resin, chloroprene rubber, polybutadiene, polybutene and/or polyisobutylene. The carbon black is pref. furnace black and/or acetylene black. The mixture is used for the vertical waterproof of an insulating- and electric power-cable.
