To attain mechanical and electrical contact having a simple structure, low cost and high accuracy, and withstand long-term use.
When an upper housing part 12 and a lower housing part 14 are arranged facing each other and fixed, a through hole, formed by linking the first hole 18 to the second hole 26, has a shape of a comparatively long tunnel space having a diameter smaller than the swelled hollow space, formed by a second hole constitution part 22 and a second hole constituting part 30. The first spring part 52 can control a load pressing a spring 16 onto an electronic device terminal in a design step, to thereby acquire proper electrical contact. The second spring part 56 generates a load pressing a spring lower part 36 onto the board side 48 of an apparatus testing device, to thereby enable superior electrical contact, by pressing the housing and the board of the apparatus testing device onto the board with a constant load at all times.
