PROBLEM TO BE SOLVED: To obtain an electrode support tube with superior circularity and straightness and even void rate. SOLUTION: In this method, a non-sintered molder 10 is received on a support member 11 in its free state and is sintered, whereby the thermal expansion and contraction can be arbitrarily performed, a load distribution does not deviate, and void rate is uniform over full length while maintaining circularity and straightness. A powder 13 with the same composition as the electrode support tube is laid on an inner circumference of the support member 11, whereby chemical reaction occurs between the support member surface and the electrode support tube surface during high-temperature sintering, so that the molder 10 and the support member 11 are not in contact with each other, and electrochemical characteristics of the electrode support tube is prevented in advance from being damaged. |
