The invention relates to a medical high-efficient sterilizing mask. The mask is a laminated structure and orderly comprises a first non-woven cloth layer, a sterilizing layer and a second non-woven cloth layer from outside to inside; the sterilizing layer is composed of a polypropylene fiber and a nano-zinc oxide doped with erbium element, wherein the polypropylene fiber and is 90-95 parts by weight, the nano-zinc oxide doped with erbium element is 5-10 parts by weight; the grain diameter of the nano-zinc oxide doped with erbium element is 50-200 nm. The medical mask overcomes the difficulty that the sterilizing performance of the existing medical mask should be improved, significantly improves the sterilizing effect of the medical mask, ensures that the medical mask can effectively cut off the bacterial spreading, and guarantees the public health.
