<p>The present invention provides: a film antenna which exhibits excellent electrical characteristics in a high-frequency region; and a resin film for use in the film antenna as the substrate. Specifically, the present invention provides a film which is for use as an antenna substrate and which is manufactured using a resin composition which comprises (A) a vinyl compound represented by formula (1), (B) an elastomer, (C) a urethane prepolymer that contains two or more isocyanate or blocked isocyanate groups in one molecule, and (D) a silane coupling agent and in which the content by mass of the component (B) is 10 to 90% relative to 100% of the component (A). In formula (1), R1 to R7 are each hydrogen, alkyl, or the like; X in the -(O-X-O)- moiety is a diphenylene skeleton; Y in each -(Y-O)- moiety is a phenylene skeleton; Z is an organic group; a and b are each an integer of 0 to 300, with the proviso that a case wherein both are 0 is excepted; and c and d are each an integer of 0 or 1.</p> |
