Abstract
A probe card comprises a connecting board and a conversion board. The connecting board has first terminals on a first surface and second terminals on a second surface. The first terminals are electrically connected to the second terminals via electric wiring. The conversion board, smaller than the connecting board, has third terminals on a third surface and fourth terminals on a fourth surface. The third terminals are electrically connected to the fourth terminals via electric wiring. The fourth terminals on the fourth surface are arranged in an area narrower than that in which the third terminals are arranged on the third surface. The second terminals have resilient terminals, which are resiliently brought into contact with the third terminals.
