PURPOSE:To make it possible to secure a high dielectric breakdown strength to the impulse voltage and to make the terminal shorter by providing a thin semiconductive layer contacted to an auxiliary conductor exposing part, an insulator exposing part, and a main conductor connection of a low surge impedance conductor to be terminal- processed. CONSTITUTION:The terminal at the grounding side of a low surge impedance conductor has a semiconductor layer 22 to contact to an auxiliary conductor exposing part 31 and a main conductor connection 13 of a low surge impedance conductor to connect. As a result, even when a large potential difference is generated instantly between a main conductor 1 and an auxiliary conductor 3 by the invasion of the lightening surge, the potential difference is divided evenly in the longitudinal direction by the resistance of the semiconductive layer 22, no large potential gradient is generated immediately above the main conductor, and the dielectric breakdown value by the impulse voltage is increased compared in the case of no semiconductive layer 22. Therefore, the terminal can be made shorter. And since an auxiliary conductor grounding metal 6 connected electrically to the auxiliary conductor exposing part 31 is provided, the grounding work of the auxiliary conductor 3 can be carried out simply by only connecting a grounding wire to the grounding metal 6.
