Provided are a probe card, a test apparatus having the probe card, and a test method using the test apparatus. The probe card includes a probe substrate having a signal line, a probe needle connected to the signal line and fixed to the probe substrate, and a cooling unit for cooling the temperature of the probe needle. Therefore, the probe needles contacting each chip can be maintained at a certain low temperature without increasing the temperature. As a result, it is possible to pervent deformation of the probe needles and minimize an amount of impurities stuck to the probe needles.
