Abstract: The invention discloses an IGBT module testing device, which comprises a testing tool comprising probes and having a fixed position, and a hot plate used for fixing an IGBT module, wherein the hot plate can drive the IGBT module to move in the direction of the testing tool, so as to realize contact of needle-shaped terminals of the IGBT and the probes; and conductive sheets are arranged between the needle-shaped terminals and the probes, and each conductive sheet comprises an inclined end which is to be in contact with the corresponding needle-shaped terminal and a horizontal end which is to be in contact with the corresponding probe. The IGBT module testing device improves the stability of tests, eliminates the mechanical damage caused by the needle-shaped terminals of the IGBT module during the test process, and prolongs the service life.
