摘要：
A method of manufacturing a hollow fiber includes the steps of:extruding a spinning solution of high molecular weight compound dissolved into a solvent, from an annular slit; and simultaneously extruding a liquid consisting of at least one of the solvent and swelling liquid capable of swelling the high molecular weight compound from an orifice encircled by the annular slit.
