摘要： A filtering medium which is unchanged in the maximum pore size even when heating sterilization, high temperature filtration, etc. are carried out, yet has a high tensile strength, can be processed into pleat-form and also is applied to high precision filtration, is provided, which filtering medium is a product having a non-woven fabric composed of 20 to 80% by weight of lower melting point microfine fibers and 80 to 20% by weight of higher melting point microfine fibers having a melting point higher by 10.degree. C. or higher than that of the lower melting point microfine fibers, the respective fibers being hot-melt-adhered to one another through the lower melting point microfine fibers, hot-melt-adhered to a hot-melt-adhesive net, and having a maximum pore size of 120 .mu.m.
