Abstract: A funnel component is manufactured by the following processes: forming a first intermediate product that is tapered, by rolling the blank material; forming a second intermediate product by folding back and welding a narrow opening side portion of the first intermediate product; forming a third intermediate product having the side wall portion by folding the wide opening side portion of the second intermediate product back outward; forming a cylindrical discharge portion forming the narrow opening side portion, a first tapered portion that connects to the discharge portion and has a tapered shape, and a second tapered portion that has a tapered shape having a taper angle less than the first tapered portion, by performing a drawing process on the third intermediate product.
