A method of manufacturing a fuel tank includes: an introducing process in which a molten resin sheet formed with a tank body is introduced in a forming mold; a shaping process in which a movable member abuts against the molten resin sheet to form a molten resin projection projected in a thickness direction of the molten resin sheet; an arranging process in which the molten resin projection is inserted in an attachment hole provided in an attachment part, and the attachment part is arranged on the molten resin sheet; and a machining process in which the molten resin projection is pressurized by a pressurizing member, so as to bulge out a portion of the molten resin projection to an outer peripheral side. |
