Abstract:
1. A method for producing a waterproof organic thin film, comprising: a waterproofing step of preparing a long laminate having an organic thin film, and bringing at least the organic thin film into contact with a waterproofing-treatment liquid; a washing step of washing at least the organic thin film surface of the long laminate; and a conveying step to be performed between the waterproofing step and the washing step, the conveying step being a step of conveying the long laminate from the waterproofing step to the washing step; wherein in the conveying step, the long laminate is conveyed while the waterproofing-treatment liquid remaining on the organic thin film surface is caused to flow relatively to the organic thin film surface, the long laminate is continuous in a conveying direction, and the conveying step comprises conveying the long laminate in the state of inclining the organic thin film surface to a horizontal plane while wind is blown onto the organic thin film surface, wherein the inclination angle of the organic thin film surface to the horizontal plane is 1 to 45 degrees, and the speed of the wind is 5 to 30 m/second.
