1. A manufacturing method for a filler element used in a flavor inhalation article, the method comprising:
processing a series of sheets while conveying each sheet along a conveyance path;
feeding a liquid additive onto an upper surface of the sheet;
forming a gathering rod during a conveying of the sheet along the conveyance path, the gathering rod being reduced in diameter by gathering the sheet, to which the liquid additive is added, in a width direction intersecting with a longitudinal direction of the sheet;
wrapping the gathering rod with wrapping paper to form a filler rod; and
cutting the filler rod into an intermediate rod having a combined length of a plurality of the filler element,
wherein the processing includes forming a crimped part in the sheet during the conveying process of the sheet, the crimped part being arranged in the width direction and extending in the longitudinal direction, and
wherein the feeding includes feeding the liquid additive continuously and dropwise onto the upper surface of the sheet, having the crimped part formed therein, entirely in the width direction of the sheet during the conveying of the sheet.
