金属網を作ることを特徴とするものである。(Means for Solving Problems) A method for manufacturing a medical noble metal net of the present invention for solving the above problems is to melt-form a noble metal net formed by braiding noble metal fine wires into a desired shape by laser processing. Then, it is characterized by making a medical precious metal net.
上記貴金属細線は、線径35μｍ〜40μｍを用い、100〜1
50メッシュの貴金属網に編組するのが好適である。The precious metal thin wire has a wire diameter of 35 μm to 40 μm, and 100 to 1
It is preferred to braid into a 50 mesh noble metal mesh.
