PROBLEM TO BE SOLVED: To provide a method for manufacturing a corrugated fiberboard sheet capable of securing a high productivity and avoiding use of a wasteful paste. SOLUTION: The method for manufacturing the corrugated fiberboard sheet comprises the steps of collapsing corrugating form of corrugating paper 4 of an outside part from a part adhered with a front linerboard 9 before a corrugating top of the paper 4 of a single-faced corrugated fiberboard sheet 1 when the sheet 7 is wider than the linerboard 9 so that a paste of a sizing roll 13a may not be adhered to this part. Thus, the use of the wasteful paste is avoided. When a corrugated fiberboard 19 is formed by a double-facer, staining of a machine with the paste is prevented or adherence of the paste to a heating platen or the like and its solidification is prevented, thereby securing the high productivity.
