1. A conductive wire for electrical properties testing, the conductive wire comprising:
a copper alloy containing 0.1 to 30 mass % of silver, with a remainder being copper and unavoidable impurities, wherein
an outer periphery portion of the conductive wire includes a fibrous structure extending in a direction at an angle of 0.5° to 20.0° with respect to a length direction of the conductive wire, and
the conductive wire has a Vickers hardness of 300 HV or more and a conductivity of 57% IACS or more.
