PROBLEM TO BE SOLVED: To provide a structure of an inspection tool for a printed circuit board for performing secure relative position adjustment by using a compact and simple structure since the relative position adjustment of contact pins is indispensable to stably pick up electric signals from the circuit board as the density of printed circuit boards is increased, with respect to the inspection tool for the circuit board. SOLUTION: To cope with increasing density of printed circuit boards, inspection tools for upper and lower faces are each provided with a plate for relative position adjustment between the printed circuit board and the contact pins, a plurality of holes are provided in the plates for relative position adjustment, the relative positions of the contact pins are adjusted by a simple method relative to each of the upper and lower surfaces of the circuit board, and the plates for relative position adjustment are securely fixed by fixing pins. The inspection tool for printed circuit boards is thus provided, capable of stably picking up electric signals from the circuit board in a wide area in the inspection tool.
