A probe card including a multi-layered substrate, a plurality of needles, and a temperature controlling unit may be provided. The multi-layered substrate may include a test pattern through which a test current passes. The needles may be provided on the multi-layered substrate. The needles may be electrically connected to the test pattern and may be configured to contact an object so that the test current may be supplied to the object. The temperature controlling unit may provide the multi-layered substrate with at least one of a first temperature and a second temperature, the first temperature being higher than the second temperature. Thus, a time for setting a test temperature may be shortened. As a result, thermal deformation of the probe card and/or the object may be reduced or suppressed, and thus reliability of test result may be improved.
