Zusammenfassung:A parallelism adjusting mechanism of a probe card is provided. The parallelism adjusting mechanism can bring probes held by a probe card into uniform contact with a wafer even if a parallelism between a mounting reference surface for the probe card and the wafer as a test object10 is lost. To achieve this purpose, specifically, to adjust a parallelism of a probe card (101) that holds a plurality of probes (1) for electrically connecting a wafer (31) as a test object and a circuitry for generating a signal for a test with respect to the wafer (31), adjusting screws (22)15 as at least part of an inclination changing unit are provided. The inclination changing unit changes a degree of inclination of the probe card (101) with respect to a mounting reference surface (Si) of a prober (202) for mounting the probe card (101) thereon.
