Abstract:
1. An inspection probe card for inspecting operations of a plurality of light receiving devices formed on a substrate, the inspection probe card comprising: a plurality of vertical-type probe pins, which is disposed in a vertical direction with respect to the substrate and has elasticity in the vertical direction, for bringing lower end portions thereof into contact with the light receiving devices during an inspection; a circuit board, which is electrically connected with upper end portions of the plurality of vertical-type probe pins at a lower surface thereof, for transmitting and receiving electrical signals for inspection to and from the light receiving devices through the vertical-type probe pins; and a guide board, which is installed at a lower surface side of the circuit board, for guiding the vertical-type probe pins by allowing them to be inserted therein, wherein, in the guide board, a plurality of guide holes passing therethrough in a vertical direction is formed, and the vertical-type probe pins are inserted through the guide holes respectively, and the lower end portions of the vertical-type probe pins protrude to a lower side of the guide board, in the circuit board, a plurality of openings through which an inspection light emitted from an upper side passes is formed, and the guide board is made of a transparent material which transmits the inspection light.
