PROBLEM TO BE SOLVED: To provide a net bag for a screen basket, in which the pollution of a floor and a peripheral section resulting from the adhesion of a sludge solid matter is prevented while preventing clogging in case of the exchange of the screen basket, in which the sludge solid matter is housed, in the solid- liquid separation of a liquid to be treated for a waste water treatment facility. SOLUTION: A uniaxial oriented body made of a thermoplastic resin or the net bag 2 composed of filaments is installed detachably into the screen basket C, and the upper end section 2a of the net bag 2 or the oriented body is folded back at the upper edge of the screen basket C and projected to the outside. A cord stabbing section 2b is formed at the upper end section of the net bag 2, and a cord 2c is inserted previously to the cord stabbing section 2b. The solid matter is housed in the net bag 2, and the upper end section 2a of the net bag 2 is closed by the cord 2c and extracted from the screen basket C in case of the exchange of the screen basket C.
