The invention discloses heat insulation electric heating clothes which comprise a body (1). A power source mounting bag (2) is sewn on the inner side of the body (1); a direct-current power source (3) is arranged in the power source mounting bag (2); a controller (4) and at least one electric heating element which are connected with the direct-current power source (3) are fixed to the body (1); the controller is arranged on a left sleeve on the body (1). The electric heating element is formed by weaving conductive yarn (5) and non-conductive yarn (6); the conductive yarn (5) comprises an insulation layer (51). A metal layer (52) is arranged in the insulation layer (51); a plurality of conductive yarn cores (30) are arranged in the metal layer (52). The heat insulation electric heating clothes are simple in structure, light and good in heating effect.
