The invention provides a ferrite antibacterial stainless steel and a manufacture method thereof. A ferrite antibacterial stainless steel plate is manufactured by adding Ag-Cu binary master alloy into an ordinary ferrite stainless steel, and comprises the following chemical compositions by weight percent: no more than 0.1 wt percent of C, no more than 2.0 wt percent of Si, no more than 2.0 wt percent of Mn, no more than 0.04 wt percent of P, no more than 0.03 wt percent of S, 15.0 to 22.0 wt percent of Cr, no more than 0.1 wt percent of N, 0.10 to 1.0 wt percent of the Ag-Cu binary master alloy, and the balance of Fe and unavoidable impurities. The ferrite antibacterial stainless steel plate keeps the favorable mechanical properties and corrosion resistance of the prior steel, has bright surface, can be processed into products in various shapes, and is applied to aspects of washing machines, tableware, kitchen utensils and the like.
