Abstract

A pair of clamping arms of a wire clamper used in a wire bonding apparatus being opened and closed via the electric strain effect or magnetic strain effect of a piezoelectric element. With the use of a piezoelectric element that expands when energized to open the clamping arms so as to release the wire held by the clamping arms, the overall weight of the wire clamper can be small, a quick clamping action is secured and the clamping force which is easily adjustable can be steady at a set value.
