Abstract: A dropping nozzle includes: a flow passage part that includes a flow passage that molten glass passes through; and an opening part that includes an opening that communicates with the flow passage, the opening part dropping the molten glass as a glass drop, wherein the opening includes a plurality of inclined parts in which adjacent inner inclination angles are different from each other in a section parallel to a center axis of the flow passage part, and from among the plurality of inclined parts, a first inclined part that is closest to the flow passage part has an inner inclination angle that is smaller than an inner inclination angle of a second inclined part that is farthest from the flow passage part.
