A forming apparatus for forming a glass ribbon is provided. The forming apparatus has an axial direction extending from a first end to a second end thereof. The first end is located on an inlet side from which molten glass is supplied. The forming apparatus includes a first protruding portion and a second protruding portion that are disposed at a top thereof and extend from the first end to the second end. A channel is provided between the first protruding portion and the second protruding portion. The molten glass flows within the channel from the first end toward the second end. In a top view, a channel width of the channel continuously decreases toward the second end in a vicinity of the second end and becomes 0 (zero) at the second end. The channel width is in a direction perpendicular to the axial direction.
