ABSTRACT OF THE DISCLOSURE A supporting member of the papermaking screen in paper machines is disclosed, which is made of a sintered body consis- ting essentially of silicon nitride having a porosity of less than 0.8 %. The abrasion loss of the papermaking screen is able to be substantially reduced as compared with conventional supporting members made of alumina ceraminc, as a result of which the useful life of the papermaking screen can considerably be lengthened.
