摘 要：
PURPOSE:To prevent drop of the electric characteristics due to exfoliation of an insulation layer from a semiconductive layer by forming semiconductive layer from resin compound obtained by adding carbon black to a base polymer containing chiefly copolymer of 4-methylpenten-1-alpha-olefin.
CONSTITUTION:A conductor 1 is
covered with an internal semiconductor layer 2, which is formed by extruding a resin compound on the conductor 1, wherein the compound is formed by adding carbon black to a base polymer chiefly containing TPX copolymer.
Example of this TPX copolymer is a one composed of 4-methylpenten-1 and one or more sorts of alpha-olefin such as ethylene and propylene, wherein the copolymerized quantity of alpha-olefin shall range 3-50wt.%. This enhances

摘 要 附 图：
close contact of an insulation layer with a semiconductor layer sufficiently, and they will not be exfoliated from each other even under application of an external
force such as bending force, etc., to result in drop of the electric characteristics, etc. 主权项：
