In Cu bonding wire having a Pd coating layer on the surface improves the bonding reliability of the ball joint in a high temperature and high humidity environment, to provide a suitable bonding wire for automotive device. A Cu alloy core material, wherein the bonding wire for a semiconductor device and a Pd coating layer formed on the surface of the Cu alloy core material, bonding wires comprises the In 0.011 to 1.2% by weight, of the Pd coating layer thickness is 0.015~0.150μm. Thus, it is possible to improve the bonding lifetime of the ball joint in a high-temperature high-humidity environment, to improve the bonding reliability. Cu alloy core material is Pt, Pd, Rh, and each one or more of Ni containing 0.05 to 1.2% by weight, it is possible to improve the ball joint reliability at 175 ℃ or more of the high-temperature environment. In addition, further to form the Au skin layer on the surface of the Pd coating layer wedge bonding property is improved.
