INSULATED WIRE AND IN-VEHICLE CABLE

Provided is an insulated wire which has heat resistance and is capable of suppressing the occurrence of copper damage even if polypropylene is used as a base resin. Disclosed in the present application is an insulated wire (12) for an in-vehicle cable (1). The insulated electric wire (12) is provided with a conductor (14) formed by a soft copper wire and an insulator (16) covering the conductor (14), the base material resin of the insulator (16) is polypropylene, and a primary anti-aging agent, a secondary anti-aging agent and a copper harm resisting agent are added to the insulator (16). 本发明提供一种绝缘电线，其即便使用聚丙烯作为基材树脂，也具有耐热性并且能够抑制铜害的发生。本申请中公开了用于车载用电缆(1)的绝缘电线(12)。绝缘电线(12)具备：由软铜线构成的导体(14)和包覆导体(14)的绝缘体(16)，绝缘体(16)的基材树脂为聚丙烯，绝缘体(16)中添加有一级抗老化剂、二级抗老化剂和抗铜害剂。
