Disclosed herein are a method of and an apparatus for manufacturing cold noodles exhibiting the thin and chewy texture unique to fresh noodles, in a continuous manner through extrusion, by which the extruded noodle strips can be prevented from undergoing puffing, weight deviation and agglomeration, so as to increase the productivity. The cold noodles can be manufactured by kneading a formulated material with water to afford dough having a water content of 30.about.45%; using an extruder to extrude the dough into individually separated strips through a die maintained at a low temperature, said dough being heated to a temperature sufficiently high to induce gelatination therein by frictional force attributable to shearing force of the extruder; and cutting the strips to a predetermined length and packaging the strips.
