SOUNDPROOF HEAT DISSIPATION COVER, COVER MEMBER, AND PRODUCTION METHOD FOR SOUNDPROOF HEAT DISSIPATION COVER

A soundproof heat-dissipation cover (3) that covers a target object (2), and includes a heat-dissipation contact surface (10) having a contact part (12) contacting the target object (2). The density is 0.1 g/cm to 2.0 g/cm, the thermal conductivity is 0.1 W/m to 2.0 W/mK, and the maximum height roughness (Rz) of the heat-dissipation contact surface (10) is 50 µm to 300 µm. With an air layer formed between the surface of the target object (2) and the heat-dissipation contact surface (10) of the soundproof heat dissipation cover (3), the contact area between the surface of the target object (2) and the heat-dissipation contact surface (10) of the soundproof heat-dissipation cover (3) can be reduced, the vibration received by the soundproof heat-dissipation cover (3) from the surface of the target object (2) can be suppressed, and the secondary radiation sound from the soundproof heat-dissipation cover (3) can be suppressed. Accordingly, the soundproof performance of the target object (2) can be improved.
