PROBLEM TO BE SOLVED: To provide an electric wire for an automobile for adjusting tensile strength in various degrees in accordance with needs, using a conductor having a same diameter dimension, without changing a total conductor area. SOLUTION: The electric wire for the automobile includes the conductor formed by arranging more than seven surrounding element wires 23 of copper or copper alloy tightly in one layer around a periphery of a center single element wire 22 of stainless steel so as to surround the center single element wire 22. A wire with a larger diameter dimension than that of the surrounding element wire 23 is used for the center single element wire 22, and a lamination factor of the conductor satisfies a following expression: the lamination factor of the conductor = ä(A+B)/C}×100[%]≥85[%]. In the expression, A is a total of cross sections of the surrounding element wires, B is a cross section of the center single element wire, and C is a cross section of the conductor.
