<p>The present invention relates to a current lead-in wire device for a superconducting power apparatus. The device includes: a current lead-in wire (59) of which one side is placed in a room temperature unit and the other side is arranged on a very low temperature unit through a very low temperature container (51) to be electrically connected to a superconducting element (53), and of which the cross section is gradually reduced from one side to the other side; sliding contact points (63, 65) which touch the current lead-in wire and electrically connect the current lead-in wire to the outside; a driving unit (67) which vertically moves the current lead-in wire to allow the current lead-in wire to touch the sliding contact points at a certain position; and a control unit (73) which controls the operation of the driving unit. The current lead-in wire in the present invention is designed to minimize heat generation and heat delivery so that the cooling load can be minimized, thereby reducing the size and the operational costs of a superconducting power apparatus.
