ABSTRACT:
A method of producing a synthetic resin rod (wire), comprising:an extruding step of extruding a synthetic resin rod;a pre-cooling step of spraying a cooling medium on the rod to pre-cool the rod extruded down to a temperature (T° C.) satisfying the following condition:in-line-formulae description="In-line Formulae" end="lead"?T≦{(a softening point of the synthetic resin)+5} [° C.]; andin-line-formulae description="In-line Formulae" end="tail"?a main cooling step of letting the rod thus pre-cooled pass through water to cool the rod.
