Abstract: PURPOSE: A composite dielectric is provided to enhance adhesive force with an electrode layer and strength, thereby enhancing durability of instrumentation. CONSTITUTION: A composite dielectric comprises polymer resins(10), and ceramic dielectrics(20) which are dispersed in the membranous polymers resin. Reinforced fibers(30) selected from glass fiber, carbon fiber, and carbon nanotubes are mixed with the membranous polymers resin and ceramic dielectric. 15 weight% of the reinforced fiber is mixed based on total weight of the composite. Additionally, one or more selected from metal powder of Al, Fe, Cu, Ag, Au, Ni, W, Cr is contained in the membranous polymers resin and ceramic dielectric.
