PROBLEM TO BE SOLVED: To provide a vibration damping sink simply formed, capable of achieving high silentness, and, in a preferred embodiment, providing even an antibacterial effect. SOLUTION: This sink 1 formed of a twin vibration damping alloy has an effect for reducing noise caused by the water of a city water and, depending on the composition of the vibration damping alloy, has the antibacterial effect. Desirably, the twin vibration damping alloy forming the sink 1 is formed of either of a Cu-Al-Mn alloy, Mg-Zr alloy, Mn-Cu alloy, Mn-Cu-Ni-Fe alloy, Cu-Al-Ni alloy, Ti-Ni alloy, Al-Zn alloy, Cu-Zn-Al alloy, Mg alloy, Cu-Al-Co alloy, Cu-Al-Mn-Ni alloy, Cu-Al-Mn-Co alloy, Cu-Si alloy, Fe-Mn-Si alloy, Fe-Ni-Co-Ti alloy, Fe-Ni-C alloy, Fe-Cr-Ni-Mn-Si-Co alloy, and Ni-Al alloy.
