PURPOSE: To realize the title apparatus markedly enhanced in its function constituted so as to be mounted on a printed circuit board tester bringing a pair of probes into contact with a printed circuit board to inspect continuity or to measure a resistance value.

CONSTITUTION: In the probing apparatus mounted on a printed circuit board tester bringing probes 1 into contact with the wiring pattern 61 of a printed circuit board 60 to inspect continuity or to measure a resistance value, the probe holder 10 held to a probe guiding mechanism 5 provided so as to be positionally movable in a horizontal direction to move up and down, the shaking lever 3 supported in a shakable manner by the probe holder 10, the displacement detection sensor 7 having the probes 1 at one end part thereof and also having an equilibrium wt. at the other end part thereof to detect the posture change of the shaking lever and a control part 50 controlling the operation of a motor 30 driving the probe holder 10 in a vertical direction by the signal from the displacement detection sensor 7 are mounted. The position of the probe 10 in a vertical direction is controlled corresponding to the posture of the shaking lever 3.
