PROBLEM TO BE SOLVED: To provide a high-strength screw.SOLUTION: A screw 1, a diameter of which is in the range of 0.3-1.4 mm, includes a resin and carbon fibers that are dispersed in the resin and the diameters of which are in the range of 0.01-0.2 μm. Preferably, the fiber length of the carbon fiber is in the range of 10-20 μm. Preferably, the carbon fiber is a vapor-phase growth carbon fiber. Preferably, the content of the carbon fibers with respect to the resin is in the range of 1-15 wt.%. |
