PURPOSE: To improve the working efficiency for inspecting a printed circuit board.

CONSTITUTION: The title method is provided with a clip-shaped ground terminal 2 for contacting the ground of a printed circuit board 1 and inspects the printed circuit board 1 by a probe 3 for probing the measurement point on the printed circuit board 1 and a through hole 5 for grounding with a land part commonly is formed adjacently on the printed circuit board 1. By inserting ground terminal pieces 2a, 2a of the probe 3 into each through hole 5, a substrate thick part between the through holes is held and the ground terminal 2 is retained on the printed circuit board 1.
