Abstract
Abstract A filtering device for blood platelet comprises polyester fibers having an average cross-sectional diameter of 0.1 to 5 mu m, wherein there is formed electro-microscopic roughness on the surface of the polyester fibers. According to the present invention, there can be realized a filtering device for blood platelet having simple construction, wherein blood platelet is caught efficiently and the removal of blood platelet is carried out in a short time.
