Claim:
1. A probe device for performing an electrical test of a semiconductor device formed on a semiconductor wafer, the probe device comprising: a mounting table configured to mount the semiconductor wafer; a driving mechanism configured to bring a probe into contact with an electrode of the semiconductor device when the semiconductor wafer is mounted on the mounting table; and a temperature control mechanism configured to control a temperature of the mounting table, wherein the mounting table includes a first electrode that is disk-shaped, a second electrode that is disk-shaped, and a insulating plate that is disk-shaped and interposed between the first electrode and the second electrode, and wherein the first electrode, the second electrode and the insulating plate are fixed to each other at a fixing part provided at their respective centers and are locked to be relatively movable to each other in a diametric direction at a locking part provided at an outer side of the fixing part in the diametric direction, the locking part being provided in the mounting table.
