A sound-absorbing panel to be used affixed to a jet engine of an aircraft, provided with: a resin core layer having a first surface, a second surface disposed on the side opposite from the first surface, and multiple partitions extending between the first surface and second surface so as to partition multiple cells; a resin first skin layer laminated on the first surface of the core layer; and a resin second skin layer laminated on the second surface of the core layer. The first skin layer is disposed so as to face the external space while in use, and has multiple through-holes for providing communication between internal spaces of the multiple cells and external space faced by the first skin layer. The core layer has openings for providing communication between the internal spaces of the multiple cells and external space of the core layer.
