Claim Text:
1. A probe apparatus for measuring static characteristics or dynamic characteristics of power devices by electrically connecting multiple probes with multiple electrodes of each of the power devices of a target object, the probe apparatus comprising: a movable mounting table that mounts the target object on which multiple power devices are formed; a probe card that is provided above the mounting table and has the multiple probes; a conductive film electrode formed on at least a mounting surface of the mounting table; a first measurement line that electrically connects the conductive film electrode to a tester via the probe card and measures the dynamic characteristics of the power devices; and a second measurement line that electrically connects the conductive film electrode to the tester and measures the static characteristics of the power devices, wherein the conductive film electrode includes a first conductive film electrode member formed on the mounting surface of the mounting table and a second conductive film electrode member formed on a side surface of the mounting table, the second measurement line electrically connects the second conductive film electrode member to the tester, and the second measurement line includes a switch device configured to open and close the second measurement line between the second conductive film electrode member and the tester.
