Disclosed is a device for measuring contact resistance of an electric vehicle charger outlet connector. According to one aspect of the present invention, device for measuring contact resistance of an electric vehicle charger outlet connector comprises: a housing; and a measuring portion formed and protruding from one end of the housing, and including a plurality of contact resistance measurement modules which are inserted into a plurality of fastening terminals of an outlet connector provided in an electric vehicle charger to individually measure contact resistance of each fastening terminal. In addition, each contact resistance measurement module comprises: a coupling portion formed to be inserted into a terminal insertion hole of a corresponding fastening terminal and formed with a first conductor portion and a second conductor portion insulated by an insulating portion; a power supply portion applying power to the coupling portion; a voltage measuring portion connected to the first conductor portion and the second conductor portion and measuring a voltage flowing through the first conductor portion, the fastening terminal, and the second conductor portion by the power applied from the power supply portion; and a contact resistance measurement portion measuring contact resistance of the fastening terminal based on the measured voltage. Therefore, overheating and fire which can occur while charging an electric vehicle can be prevented.
