Disclosed is a pantograph contact resistance measuring device. According to the present invention, the pantograph contact resistance measuring device includes: a power supply unit; a current path forming unit for forming a current path through which the current applied from the power supply unit passes through both a first contact point and a second contact point at which a feeding electrode of a pantograph and a receiving electrode of an electric vehicle are in contact, respectively; a both ends voltage measurement unit connected to both ends of the first contact point and the second contact point to measure voltages at both ends of the first contact point and the second contact point; and a contact resistance measurement unit for measuring contact resistance between the first contact point and the second contact point using the voltage measured by the both ends voltage measurement unit. Therefore, the contact resistance of the two contact points can be easily measured by measuring the voltages at both ends of the two contact points where the feeding electrode of the pantograph and the receiving electrode of the electric vehicle are in contact.
