A substrate film modified in adhesiveness which comprises a base film comprising a thermoplastic resin film containing substantially no particle, an adhesiveness-modifying layer formed on one side of the base film, and a coating layer formed on the other side. The adhesiveness-modifying layer comprises at least one resin selected among a polyester resin, urethane resin, and acrylic resin and inorganic particles. The adhesiveness-modifying layer has been formed through coating fluid application in an amount of 3-12 mg/m2 and has surface protrusions having a height of 100 nm or larger, the feet of the surface protrusions having a maximum diameter of 10 µm or larger on the average. The coating layer comprises a polyester resin and a titanium compound. |
