Contact unit and inspection system

This invention provides a contact unit that is capable of easily aligning the terminals formed on an article to be inspected and conductive contacters, and an inspection system employing such contact unit. The contact unit (2) comprises conductive contacters (3) disposed in a line pattern corresponding to the terminals formed on the article to be inspected for receiving and transmitting signals, a holding board (4) for holding conductive contacters (3), a contact block (5) disposed in a region on the holding board (4) and corresponding to a holding region of the conductive contacters (3), and a fixing member (6) for fixing the contact block (5) on the holding board (4). The fixing member (6) is fixed on the holding board (4) with screw members (13) in a central side of the holding board with respect to the region where the conductive contacters (3) are held, the fixing member (6) has a function of fixing the contact block (5) on the holding board (4) by applying a pressure through a pressing surface (11a) on
