PROBLEM TO BE SOLVED: To provide a method of manufacturing a corrugated cardboard which can easily manufacture the corrugated cardboard in which waveform cores each having a waveform of a direction inclined to an edge are superposed and connected and which is easy to prevent a stencil from being wasted. SOLUTION: The manufacturing method for the corrugated cardboard 10 comprises the steps of forming at least a pair of waveform cores 13, 14 through shaping many waveforms 16, 17 with predetermined wave directions D1, D2 in the stencil 21 for the core, disposing the waveform cores 13, 14 between a front liner 11 and a rear liner 12 superposed so that the wave directions D1, D2 cross each other, and bonding them. After at least a pair of waveform cores 13, 14 are formed, through shaping the waveforms 16, 17, so that the wave directions D1, D2 are inclined at different angles to the edge 21a of the stencil 21 for the core, the edges 21a are aligned, the wave cores 13, 14 are superposed and connected.
