SOUND INSULATION SHEET MEMBER AND SOUND INSULATION STRUCTURE USING SAME
An object of the present invention is to provide a structural body that has high vibration damping and high sound-insulating performance which exceeds mass law while being relatively light weight, that is highly flexible in design, excellent in versatility, and easy to manufacture so that productivity and economic efficiency can be improved. The object thereof is achieved with a sheet member of a sheet having a thickness of 1 mm or less and having rubber elasticity and a resonant portion, wherein the resonant portion is provided in contact with a surface of the sheet, the resonant portion including a base part and a weight part, and the weight part being supported by the base part and having a larger mass than the base part.
