Abstract
A conductive block is formed with a first face, a second face and a through hole connecting the first face and the second face. A contact probe is provided with a conductive pipe and a conductive plunger, retractably provided in at a first end of the pipe, the plunger being to be brought into contact with a device to be inspected. A first retainer includes a first insulative member through which the first end of the pipe is retained in the vicinity of the first face of the block, such that the pipe is coaxially held within the through hole while forming a gap between an outer periphery of the pipe and an interior wall of the through hole.
