PROBLEM TO BE SOLVED: To provide an approximately bowllike container in which the shape of the bottom part which can be molded with a paper is approximately spherical. SOLUTION: A paper-made container is prepared by using an approximately fanlike paper-made sheet with a number of channel parts in the short arc side part direction. The fanlike paper-made sheet is wound on an approximately deep bowllike and wooden bowllike mold for molding in which the bottom direction is formed into a curved face, to mold it into a bowl with a bottom part cavity, and in addition, a bottom part sheet is arranged in the bottom part cavity to seal the bottom part to prepare an approximately bowllike paper-made container.
