The present invention relates to a light guide tube, which is formed by weaving a plurality of filaments to provide a single-hole or multi-hole tube. Further, the filaments include filaments that are made of at least one light-transmittable material. With the single-hole or multi-hole tube formed by weaving filaments, besides strengthening the capability of enduring sideways stress, a light-emitting unit can be additionally included at a front end of the tube for illumination purposes and formation can be achieved by using various types of filaments to suit practical needs, such as combination with metal wires or electrical signal carrier material for purposes of transmission of electrical power or electronic information, thereby achieving a wider range of applications that the conventional tubes.
