The invention relates to an electrode lead. The electrode lead includes a lead and an electrode. The lead includes at least one sub-lead. The sub-lead includes a lead core structure, a first insulating layer, and a carbon nanotube composite structure. The first insulating layer is covered on the surface of the lead core structure. The carbon nanotube composite structure is winded to the surface of the first insulating layer. The electrode is set on one end of the lead and electrically connected to the lead core structure of at least one sub-lead. The invention also relates to a pacemaker using the electrode lead.本發明提供一種電極線,包括一導線及一電極頭,所述導線包括至少一子導線,其中,所述子導線包括一芯線結構、一包覆於該芯線結構外表面的第一絕緣層及一纏繞於該第一絕緣層外表面的奈米碳管複合結構,所述電極頭設置於所述導線的一端部且與所述至少一子導線中的芯線結構電連接。本發明也涉及一種採用上述電極線的起搏器。100‧‧‧起搏器10‧‧‧脈衝發生器20‧‧‧電極線22‧‧‧導線23‧‧‧電極頭30‧‧‧連接元件40‧‧‧固定元件42‧‧‧固定環44‧‧‧固定翼
