Abstract

The present invention provides a decorative film for film insert molding, the decorative film having: a fluorine-based resin layer containing 100 to 80 parts by mass of a fluorine-based resin and 0 to 20 parts by mass of a methacrylic acid ester-based resin; an acrylic-based resin layer containing 50 to 0 parts by mass of a fluorine-based resin and 50 to 100 parts by mass of a methacrylic acid ester-based resin; and a decorative layer containing a thermoplastic resin, laminated therein in this order, wherein the fluorine-based resin layer has a thickness of 10 μm to 200 μm, and surface unevenness is formed on a surface of the fluorine-based resin layer, the surface being on the side that is not in contact with the acrylic-based resin layer. The present invention also provides a method for manufacturing the decorative film for film insert molding.
