PROBLEM TO BE SOLVED: To provide a line impressing member which can impress a clear line on a prescribed position of a corrugated board sheet. SOLUTION: One side of a strip-shaped plate 11 is made a line impressing part 12. On the surface of the line impressing part 12, dimples 13 so sized as to be installed within the surface are formed at intervals in the direction of the length of the line impressing part 12. On the occasion of impressing a line when the corrugated board sheet is pushed in, protuberances are made to be brought about at positions of the liner of the sheet corresponding to the dimples 13. The liner is prevented from shifting in the direction intersecting the direction of the length of the line impressing part 12, by engagement of projections formed of the protuberances with the dimples 13.
