Abstract: PROBLEM TO BE SOLVED: To exert uniform pressure on each terminal of an object to be tested without causing undesired shearing force to act thereon, by making up a testing device out of a rotary member, a press-member support body for pressing a surface of the object to be tested rockably provided on the rotary member, and a guide member for allowing relative movement of the press-member support body. SOLUTION: With a turning plate 14 inverted, a semiconductor element 26 is mounted in an opening part of a positioning member 24. The turning plate 14 is pushed in the direction of an arrow L against energizing force of a coil spring 40 by an opening/closing operation member 4, and the turning plate 14, following a guide member 12, makes turning motion from its inverted state in the direction that approaches the positioning member 24. A press-member support body 16 rotates while being guided by a guide hole 12a in the guide member 12. When the turning plate 14 makes further turning motion, an end face of the press-member support body 16 becomes vertical to the turning locus of the center of the turning plate 14 by being guided by the guide hole 12a of the guide member 12, and as a result, the surface of a pressing part 34a of a pressing body 34 becomes parallel to a pressed surface of a semiconductor element 26.
