RESIN CERAMIC COMPOSITE MATERIAL, METHOD FOR PRODUCING THE SAME, COMPOSITE MATERIAL SHEET, FILM CAPACITOR AND MULTILAYER CAPACITOR

摘要

PROBLEM TO BE SOLVED: To obtain a resin ceramic composite material that has a relatively high dielectric constant and is suitable for forming the dielectric layer of a multilayer capacitor. SOLUTION: The resin ceramic composite material comprises ceramic particles in the volume ratio of 60-70% dispersed in a resin. The ratio of the number of neckings between ceramic particles and other ceramic particles is made≥40% in a state in which when the diameter of the mutually contact part of adjacent first and second ceramic particles 1 and 2 is 2a and the diameter of the first ceramic particle 1 is 2R, a condition in which a/R is≥0.3 is defined as the necking and in a surface element of 1μm square on an arbitrary cross section, the ratio of the number of surface elements in which the area ratio of the ceramic particles is≥40% is made≥90%.
