Abstract: An acoustic panel for an aircraft turbojet nacelle, of the type including an outer skin, an inner skin, and a cellular core which is interposed between the outer skin and the inner skin, includes a plurality of corrugated strips, each corrugated strip extending longitudinally in length while forming a succession of bosses and recesses, the corrugated strips arranged to delimit cells which extend globally perpendicularly to the skins. Each corrugated strip extends in width from a first end forming an outer folded edge, which bears on the outer skin, to a second end forming an inner folded edge, which bears on the inner skin.
