PURPOSE: To provide a cooling and drawing device which can produce a patterned fiber web at a low cost without needing an electrostatic filament- opening device for electrostatically charging filaments. CONSTITUTION: This cooling and drawing device 1 is disposed in a process for producing a fiber web 14, has an inlet for the flow of many melt-spun filaments 13, an exit for the flow of the filaments 13, and both side surfaces extended in the lateral direction in a mutually facing and separated posture between the inlet and the exit, and is used for cooling and drawing the filaments 13 which pass through a space between both the side surfaces. Therein, many mountain portions arranged in the width direction at a prescribed distance and many valley portions extended between the mountains are formed on at least one of both the side surfaces.
