The present invention relates to a sound-absorbing panel in which the structure of a vibration type sound-absorbing panel for absorbing and offsetting sound waves belonging to a low frequency band is modified to improve a sound absorption effect. A sound-absorbing panel comprises a panel body opened on a lower end thereof and formed on the lower end thereof with a rib which extends outward by a predetermined length, and a plurality of sound-absorbing holes defined on an upper surface of the panel body and possessing a sectional shape of a predetermined figure, each sound-absorbing hole being tapered downward to have an inside space which has a gradually decreasing size and then linearly perforated to have an inside space which has a constant size.
