A ground color main extruder 9 which supplies a ground color resin that is to cover a strand conductor 3 is disposed. Plural stripe sub extruders 21 and 31 which supply a colored resin in a strip-like manner in a longitudinal direction of the strand conductor 3 simultaneously with extrusion of the ground color resin are disposed. Insert molds 16 and 17 are multiply disposed.
