The present invention is provided to quickly and efficiently inspect a plurality of CCD sensors. In the present invention, a plurality of openings is formed in a circuit board of a probe card. A plurality of vertical-type probe pins is connected to a lower surface of the circuit board. A guide board is installed at the lower surface of the circuit board, and respective probe pins are inserted into respective guide holes of the guide board. The guide board is made of a transparent glass board. During an inspection, inspection light emitted from a test head passes through the openings of the circuit board and the guide board, so that it is irradiated onto the plurality of CCD sensors on the substrate. Since the plurality of probe pins can be arranged at a narrow pitch without blocking the inspection light, adjacent CCD sensors on the substrate can be inspected simultaneously.
