The present invention provides an electrical connecting apparatus that does not cause lack of mechanical strength in a probe board. The electrical connecting apparatus comprises a probe board spaced from a support member and arranged with its one surface opposed to the support member. On one surface of the probe board is provided a fixed portion having an opened screw hole at its top portion, and on the other surface are provided probes that are connected to a tester. The electrical connecting apparatus comprises a cylindrical spacer keeping a distance from the support member to a top surface of the fixed portion and a male screw member screwed in the screw hole for the purpose of tightening the support member and the probe board at a distance in accordance with the length of the spacer. The probe board has a support plate in which a plurality of conductive paths penetrating in the plate thickness direction and connected to the tester are formed and a wiring plate in which wiring paths connected to the corresponding conductive paths are formed, whose one surface is fixed to the support plate, and on the other surface of which are provided the probes corresponding to the wiring paths. The fixed portion is constituted by a female screw member fixed to the support plate at an area where no conductive paths are formed.
