Abstract: To provide a dielectric film which is excellent in dielectric properties and stability in the electric corrosion test and which is suitable for producing a high-precision printed board.
A roll film comprising a melt-processable fluororesin as the main component and having a thickness of from 1 to 100 μm, the dimensional change rate of which is less than 1.0%, in terms of an absolute value, in each of MD and TD, when heated at 150° C. for 30 minutes and then cooled to 25° C., based on the dimension at 25° C.
