Abstract
According to the present invention, allowable displacement can be increased from an excellent stress relaxation effect achieved by applying a hinge structure while adopting advantages of a dual beam cantilever-type probe that can reduce scrub. Since the hinge structure is a structure that does not receive a moment, an effect that is the same as eliminating a moment in a conventional prove can be achieved so that stress can be evenly applied and the allowable displacement of the probe can be increased.
