PROBLEM TO BE SOLVED: To provide a nozzle, by which a thin metallic belt with a constant thickness can be manufactured and mass production is possible while maintaining dimensional accuracy so as to reduce manufacturing costs. SOLUTION: This invention relates to a nozzle 10 for manufacturing a thin metallic belt, from which molten metal is jetted. The cross section perpendicular to the direction for jetting the molten metal is corrugated, and an opening part 11 having an approximately constant thickness direction dimension is installed in the amplitude direction. Inside an insertion hole 12 of the nozzle, the inner walls are protruded and connected in the thickness direction so as to form plural connection parts 14.
