<P>PROBLEM TO BE SOLVED: To provide an electric wire which has two insulating sheath layers inside and outside and has a heat resistance property and in which a crack does not develop into the outside insulating sheath layer when exposed in a high temperature. <P>SOLUTION: The electric wire (100) is provided with a conductor (110) surrounded by an inner insulating sheath layer (120) and an outer insulating sheath layer (130). The inner insulating sheath layer (120) surrounds the conductor (110) with the sheath made by extrusion molding and has a base material which is extrusion-molded from a fine particle material (12) and a binding material (122). <P>COPYRIGHT: (C)2008,JPO&INPIT |
