Ni / Pd / Au coated electrode (a) or Au coated electrode (a) good bonding properties with, the thermal shock resistance is excellent, and a bonding wire for an inexpensive than gold bonding wires. A bonding wire (W) for for connecting in accordance with the ball bonding method, Pd, not less than 1.0% by weight of at least one element selected from Au in a total amount, 4.0% by weight, selected from Ca, Y, La, Sm, Ce a least one element in a total amount comprising 20 ppm by weight or more, less than 500 ppm by weight, the balance being made of Ag and inevitable impurities, tensile strength in a tensile strength at room temperature for
18 ~ 32kgf / mm 2, 250 ℃ It is not less than 14kgf / mm
2. If this configuration, in each of the evaluation of the continuous bonding property, the heat cycle test, the evaluation, within hwanghwaseong (sulfidation resistance) of the wires of the wire flow (wire flow) at the time of evaluation, the electric resistance, the resin encapsulation of chip damage to the 1st junction directly under , there is no practical problem.
