Disclosed is an apparatus for measuring the contact resistance of an inlet connector for an electric vehicle. The apparatus for measuring contact resistance of an inlet connector for an electric vehicle according to one aspect of the present invention comprises: a housing; and a measuring unit formed to protrude from one end of the housing and including a plurality of contact resistance measuring modules having an insertion hole installed to couple a plurality of connection terminals of the inlet connector provided in the electric vehicle to measure the contact resistance of each connection terminal. The contact resistance measuring module includes: a coupling unit having an insertion hole for coupling the corresponding connection terminal, wherein a first conductor unit and a second conductor unit are insulated by an insulation unit and formed on the outer circumferential surface of the insertion hole; a power supply unit applying power to the coupling unit; a voltage measuring unit connected to the first conductor unit and the second conductor unit to measure the voltage flowing through the first conductor unit, the connection terminal inserted into the insertion hole, and the second conductor unit by means of power applied by the power supply unit; and a contact resistance measuring unit measuring the contact resistance of the connection terminal based on the measured voltage.
