Abstract (en)
A sound insulating plate effectively insulates audible noise produced by a mechanism. The sound insulating plate according to the present invention, which is disposed onto the external surface of the mechanism producing audible noise so as to closely cover the part, comprises a metal base plate, a low-density thermoplastic resin layer fixed to the metal base plate, and an external high-density heat-hardened resin layer obtained by heating the low-density thermoplastic resin layer. The material of the low-density thermoplastic resin layer is a foam resin such as polyurethane or polyamide.
