PROBLEM TO BE SOLVED: To provide a super conductive accelerator with reduced number of assembly man-hours, improved cleanness of a superconductive accelerator cavity, without problem of leakage during operation. SOLUTION: The superconductive accelerator is constructed of a superconductive acceleration cavity 23 with beam pipes at both ends, a liquid helium container side plate with large diameter 25 connected to the one end part of the superconductive acceleration cavity along longitudinal direction of the same by welding through a joint ring, a liquid helium container side plate with small diameter 26 connected to the other end part of the superconductive acceleration cavity along longitudinal direction of the same by welding through the joint ring, a liquid helium container body plate 27 arranged at the body side of the superconductive acceleration cavity connected disassemble feasibly, to the liquid helium container side plate with large diameter and the liquid helium container side plate with small diameter, and a vacuum container 21 housing the superconductive acceleration cavity.
