For the purpose of reducing noise entering from outside and cross talk to a practically negligible extent even when using covered conducting wire made of only conducting wires and insulators, a multi-probe unit has a plurality of probes for contact with a plurality of conductor patterns to be inspected which are aligned side by side, in which every two adjacent ones of the probes for contact with odd-numbered one and even-numbered one of the conductor patterns are positioned in upper and lower levels distant in the thickness direction, and a shield plate of a conductive material having an electrically shielding function is interposed between the upper and lower probes.
