To manufacture a pressure container having high reliability, in which joined parts are hardly damaged by pressure inside the pressure container, vibration of the pressure container, or the like, and also having long service life.
The manufacturing method of the pressure container includes: a step of forming a taper part T by spreading one end of a copper pipe outward with a prescribed inclination; a step of inserting the pipe into the through-hole of a container body part and by bringing the tapered face of the taper part T into contact with a face to be the inner side face of the pressure container; a step of energizing with pressurizing force applied between the pipe and the container body part and joining the taper part T of the pipe to a corner part surrounding the through-hole of the container body part; and a step of combining the container body part joined to the pipe with the other container body part and joining them to each other so that the pipe is positioned inside the pressure container.
