A nano-silver wire structure includes a substrate layer and a nano-silver film layer, which mainly limits the thickness ratio of the substrate layer to the nano-silver film layer and the size of the nano-silver microparticles in the nano-silver film layer, in order to achieve a better silver ion release rate, thus, the sterilizing effect of silver wire body in liquid is better.本發明提供一種奈米銀絲結構，主要係包括一基材層及一奈米銀薄膜層，而本發明主要透過同時限定基材層與奈米銀薄膜層之厚度比以及奈米銀薄膜層中之奈米銀微顆粒的粒徑大小，以達到較佳的銀離子釋出率，進而使銀絲本體置於液體中的殺菌效果更佳。
