ABSTRACT:
An object of the present invention is to provide a damping and soundproofing member not only excellent in an excellent damping and soundproofing effect but also excellent in easiness of forming thereof, especially capable of forming directly a damping and soundproofing layer on a substance to be adhered and further excellent in lightness, washing ability, durability, and the like.The invention relates to a structure formed by laminating cured product layers formed from plurality of fluid resin compositions on a substrate expecting a damping or soundproofing effect, wherein at least two cured product layers of the above cured product layers are different in hardness. Moreover, preferably, no part of the hardest layer in the above cured product layers is directly formed on the substrate and the hardest layer is formed on the substrate via an intermediate layer.
