A probe device includes an electrode plate arranged above a mounting table for mounting thereon a semiconductor wafer and electrically connected to a tester, a contact probe arranged at a side of the mounting table and electrically connected to a mounting table electrode of the mounting table. The contact probe includes a contact portion, having a top surface formed unenven, to be in contact with the electrode plate, and a cable connection portion formed as one unit with the contact portion. The contact portion and the cable connection portion are vertically movable by a biasing member provided below the cable connection portion. When the probes are made contact with electrodes of a semiconductor device of the semiconductor wafer by moving up the mounting table, the contact portion and the electrode plate are made contact with each other and the backside electrode and the tester are electrically connected to each other. |
