<P>PROBLEM TO BE SOLVED: To provide a method for producing a corrugated material without applying press force onto a sheet-like base material and without excessively applying tensile force thereonto in forming the base material into a corrugated shape. Ž<P>SOLUTION: An apparatus for producing the corrugated material includes the following scheme: A plurality of rods 21 and 22 with respective tapered front guides 41 and 42 are collocated so as to be set apart from one another. The respective tips 51 and 52 of the rods 21 and 22 are so designed that the spacings in the height direction of the adjoining tips 51 and 52 are made greater than the thickness of a base material 1 to ensure the base material 1 to be guided smoothly into between the tips 51 and 52. Thus, the base material 1 is ensured to form corrugatedly while moving in the longitudinal direction of the rods 21 and 22 and passing through the respective spacings between the rods 21 and 22.
