A composite dielectric material and a capacitor with this material are provided. The material has a main body with a thermoplastic polymer, and a plurality of particles, particularly nanoparticles, dispersed in the main body, wherein the particles are made of a dielectric ceramic material. Each of the particles is at least partially coated with a shell of the thermoplastic polymer. A method of manufacturing and a capacitor utilizing the composite material are also disclosed.

The present invention relates generally to the fields of electrical engineering and electronics. More specifically, the present invention relates to passive components of electrical circuit and more particularly to a capacitor intended for energy storage and method of production thereof.

A resin composition capable of providing a film or the like that can suppress coloration even after heating is provided. Further, a molded product, a film, a conductive film, a film capacitor, a polarized material, an electrostatic induction conversion device, and a touch panel using the resin composition are provided. A resin composition including: a copolymer (A) containing a constitutional unit (a1) derived from 1,1-dicyanoethylene and a constitutional unit (a2) derived from a compound represented by the following general formula (I); and a Bronsted acidic compound (B), in which a content of the Bronsted acidic compound (B) in the resin composition is 0.1 to 95,000 ppm by mass.
