The present invention provides a non-contact electric wire reel (10) including: a cable (100) including a plurality of electric wires extending by sequentially including a first electric wire portion (110), a second electric wire portion (120) and a third electric wire portion (130) in its longitudinal direction; a rotation drum (200) configured to allow the cable (100) to be wound on or unwound from its outer circumferential surface, and including one or more rotation holes (210, 220); and a fixation portion (300) including a fixation hole (310) remaining fixed against the rotation of the rotation drum (200), wherein the second electric wire portion (120) of the cable (100) is disposed in a twist section partitioned by the rotation holes (210, 220) and the fixation hole (310), and twisted or untwisted by the rotation of the rotation drum (200).Accordingly, the present invention may supply a large amount of power to a load by allowing the electric wire (100) to be wound on or unwound from the rotation drum (200) without using any contact such as a slip ring or a brush.
