Fluororesin film, metal-clad laminate and substrate for circuit

Abstract

Provided is a fluororesin film with high uniformity in adhesion strength of the film. A fluororesin film that is a film comprising a fluororesin-containing composition, wherein at least one surface of the fluororesin film has an average value of contact angles for water measured at 5 points with intervals of 100 mm in a travel direction of 105° or less and an average value of contact angles for n-hexadecane measured at 5 points with intervals of 100 mm in the travel direction of 45° or less at locations of center and 100 mm from respective left and right ends.

Dependencies are inferred from the claim text.
