PROBLEM TO BE SOLVED: To implement stable processing, for example when a palladium surface is coated with a chemical solution, by adjusting the level of wettability appropriately and suppressing the rate of change of the wettability with the passage of time to a regular value or below in a palladium film taken from a palladium film roll. SOLUTION: In a method for producing the palladium film roll, while a palladium membrane is formed on a plastic film by a vacuum membrane forming method, it is taken up in the shape of a roll, after that, the first winding back is carried out in the atmosphere within 720 hr and the winding back is carried out in the atmosphere at least one time.
