PROBLEM TO BE SOLVED: To provide a method for degassing and sealing a vessel for powder pressurized sintering with which the sealing having high reliability can be obtained. SOLUTION: In the method for degassing and sealing the vessel for powder pressurized sintering, arranging a pipe for removing the air; this method is performed as the followings, that is, after removing the air in the vessel for powder pressurized sintering, a flat part is formed by pressing the pipe for removing the air in this diameter direction, at least one position of a welding part crossing the pipe for removing the air, on this flat part, is formed and successively, the above flat part at the reversed side of the above welding part to the vessel for powder pressurized sintering, is melted for cutting off and the sealing treatment is performed.
