Abstract: PURPOSE:To reduce the occurring case of a defective measurement by driving an up-and-down mechanical device for a semiconductor element which the semiconductor element mounting part is made to move up and down, at the position other than a measurement part, and easily performing a positioning of the semiconductor element. CONSTITUTION:The semiconductor element 12 being an object to be inspected is mounted on the semiconductor element mounting part 5. A cylinder 10 is begun to lower and an engaging piece installed on the cylinder 10 is engaged to an engaging part 8. When the cylinder 10 is lowered further, an up-and-down member 7 for the semiconductor element is begun to lower against an energizing force of a spring 9, and along with the member 7 going down, electric poles of the element 12 are made to lower together with the mounting part 5 to the position to contact with contacts 4.
