The present invention relates to a cooled charging cable for an electric vehicle, and the purpose of the present invention is to cool a power line by circulating, through a cooling tube or a refrigerant fluid channel, high-temperature heat generated in the power line when a large-capacity current required for rapid charging is continuously applied to the power line, and arrange the cooling tube or refrigerant fluid channel in a shaping material filled in the cable to cool the power line through a wider surface area in an indirect heat transfer method, so as to enhance the cooling efficiency while preventing the pipe or channel from being in direct contact with the power line, thereby preventing an insulation layer thereof from being deteriorated, damaged, or destructed due to the refrigerant. The cooled charging cable for an electric vehicle according to the present invention comprises: a cable part; at least one conductive part surrounding the outer surface of the cable part; at least one cooling part disposed in the conductive part; and an outer sheath surrounding the cable part and the outer surface of the conductive part.
