The surface plate 2 is superposed on the thin film body 5 and adhered by the adhesive layer 8. A soft sound insulating sheet or a metal plate is used as the sound insulating plate 6. A soft sound-insulating sheet is made by kneading a high specific gravity substance into a main base material, and molding it into a main base material such as vinyl chloride, polyethylene, polypropylene, rubber, rubber asphalt, etc., and inorganic materials such as barium sulfate, calcium carbonate, clay, etc. It is formed by kneading materials, lead powder, iron powder, metal powder such as stainless steel powder, and other high specific gravity substances. In the case of a metal plate, it is a lead plate or an iron plate. The sound insulation plate 6 is laminated on the lower surface of the sound absorbing base material 1 and adhered by an adhesive layer 8. The sound absorbing composite panel A thus formed is used as a ceiling material or a wall material for an acoustic room or the like. Then, the sound is absorbed through the sound absorbing holes 3, absorbed by the thin film body 5, the concave portion 4b and the sound absorbing groove 7, and also absorbed by the sound absorbing base material 1 and absorbed, and is also insulated by the sound insulating plate 6. The sound insulation plate 6 also serves as a construction base, and preferably has the following structure in order to improve the function as a construction base. When the sound insulation plate 6 is a soft sound insulation sheet, the soft sound insulation sheet has irregularities formed on its surface (unevenness for wedge effect at the time of adhering), and the soft sound insulation sheet has a nonwoven fabric thermocompression-bonded integrally, For example, a soft sound insulating sheet with paper attached. When the sound insulation plate 6 is a metal plate, those having irregularities formed on the surface (unevenness for expanding the bonding area and for the wedge effect), those with non-woven fabric attached, those with paper attached, unfinished untreated And the like.

るものである。As described above, according to the present invention, the sound absorbing base material is provided with unevenness on one side thereof, and a breathable thin film body is laminated on one surface of the sound absorbing base material and adhered to the projections of the unevenness to obtain a large number of sound absorbing materials. Since the surface plate with holes is bonded to the thin film, the sound absorbed from the sound absorbing holes is absorbed in the spaces of the thin film and the concave and convex recesses, and is also absorbed by the sound absorbing base material. In addition to absorbing sound, it can also reliably block sound and prevent sound from leaking, because it is much more effective in absorbing sound, and because a sound insulation plate is bonded to the other surface of the sound absorbing base material. ..
