PROBLEM TO BE SOLVED: To provide a cabinet of vibration deadening dishwasher with a simple structure that can highly reduce noise and even exerts antimicrobial effect in good cases. SOLUTION: A cabinet 2 of a dishwasher 1 is composed of bicrystal vibration deadening metal alloy and is effective in reducing noise caused by washing water and is also antibacterial depending on the composition of the vibration deadening metal alloy. It is desirable that the vibration deadening metal alloy of twin type constituting the cabinet 2 is composed of any one of 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.
