A non-contact electric wire reel including: a cable including a plurality of electric wires extending by sequentially including a first electric wire portion, a second electric wire portion and a third electric wire portion in its longitudinal direction; a rotation drum configured to allow the cable to be wound on or unwound from its outer circumferential surface, and including one or more rotation holes; and a fixation portion including a fixation hole remaining fixed against the rotation of the rotation drum, wherein the second electric wire portion of the cable is disposed in a twist section partitioned by the rotation holes and the fixation hole, and twisted or untwisted by the rotation of the rotation drum. The non-contact electric wire reel may supply a large amount of power to a load by allowing the electric wire to be wound on or unwound from the rotation drum without using any contact.
