To provide a means for efficiently and continuously drying a yarn-like material having low heat resistance and weakness like a collagen single yarn without causing heat denaturation and fracture.
This method for drying the yarn-like material comprises passing the yarn-like material to be dried in an axial direction through an air duct and applying airflow to the yarn-like material so as to carry out nearly circular motion of the yarn-like material around a straight line L as a center connecting a feed position P1 at which the yarn-like material is charged into the air duct with a take-up position P2 at which the yarn-like material is discharged from the air duct on a plane M perpendicular to the straight line L.
