PROBE UNIT AND MANUFACTURE THEREOF

PURPOSE:To provide a probe unit and manufacturing method thereof in which the contact of pins can be prevented by enhancing strength against external force when a quite thin metal wire having a diameter shorter than a specified value is employed as a probe pin, fine pitch can be dealt with while enhancing pitch accuracy by allowing holding on a resin board, and machining accuracy and productivity can be enhanced when the quite thin metal wire is arranged on the resin board. CONSTITUTION:Quite thin metal wires 4 having a diameter of 100mum or less and dielectric fibers 20 are woven like a cloth to form a prepreg 21 which is held on a resin base 3 to constitute a probe unit 1. When the probe unit 1 is manufactured, the prepreg 21 is placed in a metal mold while being applied with tension and then resin is filled in the metal mold thus forming the resin base 3. The quite thin metal wires 4 are embedded at least partially in the resin base 3.
