<p><P>PROBLEM TO BE SOLVED: To provide a vehicular electric wire conductor and a vehicular electric wire which reduce the diameter of the electric wire since it has high strength and elongation, and is superior in impact resistant energy. <P>SOLUTION: A conductor 12 which contains zinc by 25 to 45 mass% and of which the rest is constituted of a soft material of copper alloy composed of copper and inevitable impurities is used. The copper alloy may contain metal such as magnesium, tin, silver, indium, strontium, and calcium by a prescribed amount. It is preferable that the soft material of the copper alloy has tensile strength of 350 MPa or more and elongation of 10% or more. Moreover, it is preferable that conductivity of the copper alloy is 20% IACS or more. It is preferable that a cross-sectional area of the conductor 12 is 0.22 mm<SP>2</SP>or less. Then, the vehicular electric wire 10 is used in which the outer periphery of the conductor 12 is not covered by an insulator 14. It is preferable that the vehicular electric wire 10 has a length of 1 m and impact resistant energy of 40 J or more per the cross-sectional area of 1 mm<SP>2</SP>. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
