A ground color main extruder which supplies a ground color resin that is to cover a strand conductor is disposed. Plural stripe sub extruders and which supply a colored resin in a strip-like manner in a longitudinal direction of the strand conductor simultaneously with extrusion of the ground color resin are disposed. Insert molds and are multiply disposed. While alternatingly switching over the stripe sub extruders and each time when a colored resin to be supplied is changed, a colored resin of a predetermined color is supplied through a path which is disposed for each of the stripe sub extruders and
