Abstract

The problem of the present invention is to provide an aqueous composition with which the surface of stainless steel is sufficiently roughened in an efficient manner with few steps, while maintaining good quality (e.g., thickness) of the stainless steel after treatment. The above problem is solved by the following aqueous composition for roughening the surface of stainless steel. Namely, the aqueous composition comprises 0.1% to 10% by mass of hydrogen peroxide based on the total amount of the aqueous composition, 1% to 30% by mass of halide ions based on the total amount of the aqueous composition, and 0% to 3% by mass of copper ions based on the total amount of the aqueous composition.
