Patent ID: 7282378

Claim:
A method of manufacturing an inspection unit, comprising: preparing a conductive member having a first face adapted to be mounted on a board on which an inspection circuit is arranged, and a second face adapted to be opposed to a device to be inspected, the conductive member being formed with a first through hole having a first diameter and communicating the first face with the second face; preparing a contact probe comprising a tubular body having a second diameter which is smaller than the first diameter, and a plunger retractably projected from one end portion of the tubular body; disposing the contact probe in the first through hole; preparing a conductive plate having a second through hole; injecting molten resin into the second through hole such that at least a part of inner face of the second through hole is covered with solidified resin, thereby forming a third through hole; and disposing the conductive plate so as to oppose to the second face of the conductive member and to communicate the third through hole with the first through hole, wherein the solidified resin is brought into contact with at least the one end portion of the tubular body so as to coaxially retain the contact probe in the first through hole while only the plunger is projected from the conductive plate.
