Claim 0:
1. A decorative film, comprising:
a base film; and
a top layer comprising a fluorinated polymer;
wherein:
the top layer is disposed on one surface of the base film;
a surface reflection intensity Wa at a wavelength of from 0.1 to 0.3 mm, and a surface reflection intensity Wb at a wavelength of from 0.3 to 1.0 mm, of the top layer as measured by using a wave scan apparatus, in such a state that the decorative film is stretched by 1.5 times, are both at most 30.0;
the fluorinated polymer is a fluorinated polymer having crosslinkable groups or a crosslinked fluorinated polymer formed by letting the fluorinated polymer having crosslinkable groups be crosslinked;
the fluorinated polymer having crosslinkable groups comprises:
at least one unit based on a fluoroolefin;
at least one unit based on at least one monomer selected from the group consisting of a vinyl ether, a vinyl ester, an allyl ether, an allyl ester, and a (meth)acrylic acid ester; and
at least one unit having a crosslinkable group;

a content of units having a crosslinkable group in the fluorinated polymer having crosslinkable groups is from 0.5 to 35 mol % relative to all units of the fluorinated polymer having crosslinkable groups; and
the fluorinated polymer having crosslinkable groups comprises a polymer having a glass transition temperature of less than 50° C. and a polymer having a glass transition temperature of at least 50° C.
