PURPOSE: To obtain a vibration-damping sheet capable of providing high vibration-damping property by a relatively thin thickness and excellent in curved surface-attaching property and punchability and suitability for labelling.
CONSTITUTION: This vibration-damping sheet 1 is constituted of a laminate 2 obtained by laminating a support layer 3, a vibration-damping layer 4, a primer coating layer 5, an organic component barrier layer 6 and a tacky agent layer 7 in this order from the upper layer and a release paper 8 attached to the tacky agent layer 7. The vibration-damping layer 4 is a layer capable of exhibiting vibration-suppressing action and, for example, the layer 4 is composed of a vehicle consisting of the mixture of one or two or more substances selected from a group consisting of asphalt, rubbers, synthetic resins and cellulose derivatives, synthetic resin powder and an elastomer containing an elastic material having ≥500% elongation. The organic component barrier layer 6 has a function for preventing the transfer of an organic component such as a tar component or an oil component contained in the vibration-damping layer to the tacky agent layer.
