To obtain a paper container which can be used in a microwave oven and can be retort pasteurized.
A container body is comprised of a cylindrical body 120 and a bottom body 130, wherein the bottom body 130 whose outer periphey extends downward is thermally bonded to the lower end of the cylindrical body 120 in such a manner that the outer periphery of the extended part of the outer periphery of the bottom body 130 is at the same level with the lower end of the body 120. And inner and outer edges of the cylindrical body which are bonded together is covered with a laminated film 20. An opening circumferential edge member 31 is thermally bonded to the outer periphery of the upper portion of the container body, and a bottom edge annular member 33, which holds the lower end of the cylindrical body 120 and the cicumferential edge of the bottom of the container body thermally bonded to the outer periphery of the extended part of the bottom body from the inside and the outside, is thermally bonded to the lower end of the body 120 and the lower end of the bottom body 130. And the members 31, 33 are provided by injection molding molten polypropylene.
