Abstract: Provided is a solidification apparatus that makes variations in the surface height of a molten metal relatively non-affected by the proceeding speed of a metal sheet to significantly increase the proceeding speed of the metal sheet and to increase the productivity of the metal sheet. The solidification apparatus for producing a metal sheet by solidifying molten metal includes rows of rollers arranged in a proceeding direction of the metal sheet, wherein when the rows of rollers are grouped into a plurality of sections, an average of roller pitches each being a distance between centers of rollers adjacent in the proceeding direction of the metal sheet is smaller in a given section than in a preceding section.
