Claim Text:
1. An electric connecting apparatus having a working table holding on a working surface thereof a device under test having a plurality of electrodes and heating or cooling the device under test and electrically connecting the plurality of electrodes to a tester, comprising: a probe card having a probe board provided with a first surface thereof opposed to the tester and having formed therein a conductive path to be electrically connected to the tester and a plurality of probes provided on a second surface of the probe board to be connected to the conductive path so as to enable to respectively contact the plurality of electrodes of the device under test on the working table and moving relatively to the working table; and one or a plurality of elastic heat conducting member(s) arranged between the working surface of the working table or the device under test on the working surface and the probe board, wherein the elastic heat conducting member enables to abut on and conduct heat to the working surface of the working table or the device under test on the working surface and the probe board in a state in which the plurality of probes do not abut on the plurality of respective corresponding electrodes and is elastically deformable not to prevent abutment between the plurality of probes and the plurality of respective corresponding electrodes.
