PURPOSE:To prevent a contact probe from slipping off, by laying an elastic sheet on a probe plate to force the contact probe into a hole from the side opposite thereto. CONSTITUTION:A rubber sheet 9 with a hole 8 drilled according to the position of a hole 6 is applied on the top surface (F) of a probe plate 1. First, a contact probe 3 is forced in from the under surface (R) side of the probe plate 1. Here, the inner diameter P2 of the hole 6 of the probe plate 1 is formed to meet P2<=P1 as compared with the diameter P1 of a flange 7 as large-diameter part of the contact probe 3 and as the contact probe 3 is forced in, the flange 7 passes through the hole 6. With the further forcing thereof after the passage of the flange 7 through the hole 6, the hole 8 of the rubber sheet 9 is widened with the flange 7. As the contact probe 3 is being forced forward, the flange 7 passes through the rubber sheet 9 completely. Finally, the contact probe 3 is pulled back to the under-surface (R) side until the flange 7 abuts against the top surface of the rubber sheet 9 to complete the election thereof.
