A wire clamper used in a wire bonding apparatus including a pair of open/close clamping arms and a pair of clamping elements provided at terminal ends of the clamping arms so as to clamp a bonding wire in between, and at least one of the clamper arms is opened and closed by the electric strain or magnetic strain effect of a piezoelectric element. In addition, a clamping load adjustment screw is installed at the root end of the wire clamper so that it can set an initial clamping load of the clamping elements.
