PURPOSE:To easily manufacture a positive electrode vessel having a compressed part on the outer circumference and an anticorrosive film on the inner surface without causing a peeling or cracking on the anticorrosive film. CONSTITUTION:A compressed part 3 is first formed on the outer circumference of a straight metal pipe 15. Thereafter, an anticorrosive film 4 is formed by flame spraying on the inner surface of the metal pipe 15. Thus, the expansion and contraction of the metal pipe 15 generated by the flame spraying heat in the flame spraying formation of the anticorrosive film 4 is absorbed and moderated by the compressed part 3 formed in advance. Further, at the time of working the compressed part 3, the shock accompanying the working is prevented from being transmitted to the anticorrosive film 4. |
