A removal device of cable foil comprising: a fixing member configured to fix an electric wire; a foil cutting unit disposed adjacent to the fixing member to cut foil of the electric wire fixed by the fixing member; and a foil stripping unit configured to strip the foil of the electric wire, which is cut by the foil cutting unit, from the electric wire, wherein the foil cutting unit comprises: a first rotating member rotatably disposed adjacent to the fixing member (100 to be rotated by a connected first rotating shaft; a first rotation motor connected to the first rotating shaft to rotate the first rotating shaft; a pair of cutting blades slidably installed on the first rotating member so that the blades come into contact with or are released from the electric wire by a sliding movement; and distance adjustment means configured to slide the cutting blades and thereby adjust a distance between the pair of cutting blades, characterised in that the foil stripping unit comprises: a second rotating member rotatably disposed inside the first rotating member to be rotated by a connected second rotating shaft; a second rotation motor connected to the second rotating shaft to rotate the second rotating shaft; and a stripping member installed on the second rotating member to come into contact with the outer surface of the electric wire, wherein the stripping member is rotatably installed on the second rotating member, and further comprising: a third rotating shaft connected to the stripping member; and a third rotation motor connected to the third rotating shaft to rotate the third rotating shaft. a fixing member configured to fix an electric wire; a foil cutting unit disposed adjacent to the fixing member to cut foil of the electric wire fixed by the fixing member;
