Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for producing an Fe-Ni based alloy thin sheet where the problem of the reduction in efficiency is solved, and also, the generation of unevenness in the luster caused by an oxide film can be prevented. SOLUTION: The Fe-Ni based alloy thin sheet is produced by subjecting an Fe-Ni based alloy steel comprising 30 to 50% Ni to cold rolling, next cleaning the steel in such a manner that the rolling draft of a brush roll is controlled to ≥2.5 mm, then annealing the steel at a dew point of
