Abstract: A sheath core type filament, such as a hollow filament, an optical filament or a conjugate filament, even if extremely thin can be continuously stably produced through simple process without the need to use any special high-precision high-level equipment. The process is characterized in that a raw sheath core type filament fed by sheath core type filament feeding means is heated by infrared light flux and the heated sheath core type filament is oriented to 100-fold or more by tension given by the self weight thereof or tension of 1 MPa or less.
