One of the greatest feature of the spinning method of the present invention is, in a spinning method employing the so-called melt-blowing method, notches are formed in the tip portions of capillaries of a melt-blowing die. This allows, during spinning, a high-speed gas blowing from orifices of the die to flow through the notches whereby the flow of a molten resin being extruded through each capillary is divided into two parts or more. Also disclosed is a melt-blowing die having capillaries formed with these notches. According to the present invention, it is possible to prevent fibers from becoming entangled or ball-shaped.
