<p><P>PROBLEM TO BE SOLVED: To provide a film which has a high dielectric constant, is thin, and has good mechanical characteristics and high heat resistance, and to provide a raw material used for preparing the film. <P>SOLUTION: This polyether sulfone resin composition comprises (A) a polyether sulfone, (B) a phenoxy resin and (C) an inorganic filler, wherein the weight ratio of the components (A):(B) is 60:40 to 95:5, and the volume of the component (C) is 5 to 50, when the total volume of the components (A), (B) and (C) is 100. A polyether sulfone resin liquid composition comprises the polyether sulfone resin composition and a solvent. The film is obtained by casting the polyether sulfone resin liquid composition on a support and then removing the solvent, wherein the thickness of the film is 0.5 to 50μm. A film capacitor uses the polyether sulfone resin liquid composition film as a dielectric layer. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
