1. A wire harness checker for inspecting a state when and after a terminal of a terminal-fitted wire having an end fixedly fitted with said terminal is inserted into a connector housing to form a wire harness, comprising:
AC inspection signal supply means for supplying an AC inspection signal to said terminal-fitted wire at least when said terminal thereof is inserted in said connector housing;
at least one pair of electrically-conductive plates disposed adjacent to said connector housing and adapted to detect the AC inspection signal from said terminal of said terminal-fitted wire inserted into said connector housing; and
determination means for determining a position where said terminal of said terminal-fitted wire supplied with the AC detection signal from said AC inspection signal supply means is inserted in said connector housing, in accordance with a relative detection value of each detection signal of said pair of electrically-conductive plates.
