Abstract: A method of manufacturing a resin container having a flat cross-sectional shape includes a temperature adjusting step of preliminarily blowing a resin preform in a first mold to mold an intermediate molded body having a diameter larger than a diameter of a container short diameter side and adjusting a temperature of the intermediate molded body in the first mold, and a blow molding step of bringing the temperature-adjusted intermediate molded body into contact with a second mold to compress the intermediate molded body in a container short diameter direction, and then stretching and blow molding the intermediate molded body in the second mold to manufacture the resin container.
