PROBLEM TO BE SOLVED: To provide a technique for imparting a length of≥1 m to a CNT, by solving the problem that the length of a carbon nanotube (hereinafter called CNT) is too short to increase its use but chemical production of a long CNT is difficult (the current maximum length: about 20 mm), and the problem that since chemically produced CNTs include impurities (irregular shapes), a technique for separating CNTs of the objective shape from the others is required. SOLUTION: A length of≥1 m is imparted to a CNT by a surgical method (which is not chemical), that is, by direct connection with a femtosecond laser light. At this time, alignment of fine materials is enabled by using a water conveyor shown by Fig.3, and continuous welding is performed. As peripheral techniques, two Figs.4, 5 (not shown) of techniques for classifying CNTs formed by chemical synthesis into CNTs of defective shape and CNTs of regular shape and Fig.6 (not shown) of an automatic concentration technique are explained.
