COMPLEX DIELECTRIC MATERIAL

摘要

PURPOSE:To form a complex dielectric material having sufficient relative, permittivity, low dielectric loss and excellent utility by blending inorganic dielectric material powder with particulate surface coated with an electroconductive substance with a resin. CONSTITUTION:This complex dielectric material 1 consists of inorganic dielectric material powder 2 and a resin 3 and the surface of practicles 2 of the inorganic dielectric material powder is partially coated with an electroconductive substance 2a. The electroconductive substance 2a is electroconductive powder and is preferably stuck to the surface of the particles 2 of the inorganic dielectric material powder with the same resin for constituting the dielectric material. Metallic powder, carbon powder or semiconductor powder may be cited as the electroconductive powder. Electroconductive needle-like powder 4 may be used instead of the electroconductive powder 2a and a complex dielectric material 1' is produced from the electroconductive needle-like powder, the inorganic dielectric material powder 2 and the resin 3.
