摘要：
A polycrystalline silicon rod according to present invention has a structure for hanging of polycrystalline silicon rods to each other end-to-end, so that the efficiency of melting polycrystalline silicon can be increased considerably. A polycrystalline silicon rod obtained by entirely or partially removing a peripheral portion from the rod to leave a central portion, and processing the central portion, preferably, the peripheral portion is removed by grinding in an amount corresponding to 10 to 60% of the diameter of the rod, and then subjected to groove-forming processing. This makes annealing unnecessary.
