Abstract
A composite board having an excellent vibration-suppressing sound-shielding performance can be obtained by joining a plurality of board materials with each other by the intermediary of a tacky adhesive. This tacky adhesive contains, as its principal components, one or more kinds of polymers selected from the group consisting of natural rubber, synthetic rubbers, various resins (acrylic resin, silicone resin, etc.). A sheet-like base material such as a paper sheet can be used in association with the tacky adhesive layer in the composite board, and such type of composite boards have an excellent vibration-suppressing sound-shielding performance as compared to the composite boards in which the tacky adhesive layer is not associated with a sheet-like material.
