PROBLEM TO BE SOLVED: To provide a sound-proofing wall which has favorable appearance, which will not man a surrounding view, and in which a gap is hard to occur even after repeated contraction by drying or expansion by rainfall for a long period. SOLUTION: This wooden sound-proofing panel is composed of laminated lumber or width-direction laminated lumber formed by laminating laminas, with adjacent laminas bonded to each other. In this wooden sound-proofing panel, the lamina is 300-10 mm thick for improving its effect. In jointing the wooden sound-proofing panels with each other for use, the wooden sound- proofing panels having packing on a contact surface with other wooden panels are necessary at least. For supporting the wooden sound-proofing panel by columns for use, packing is bonded to a contact surface with the column supporting the wooden sound-proofing panel.
