Ceramic resin composite body

Abstract

Provided is a ceramic-resin composite body that has good mass productivity and product properties (heat dissipation properties, insulation properties and adhesive properties), and particularly a ceramic-resin composite that can dramatically improve the heat dissipation properties for electronic devices. The ceramic-resin composite body includes: 35 to 70% by volume of a sintered body having a monolithic structure in which non-oxide ceramic primary particles having an average major diameter of from 3 to 60 μm and an aspect ratio of from 5 to 30 are three-dimensionally continuous; and 65 to 30% by volume of a thermosetting resin composition having an exothermic onset temperature of 180° C. or more and a curing rate of from 5 to 60% as determined with a differential scanning calorimeter, and having a number average molecular weight of from 450 to 4800, wherein the sintered body is impregnated with the thermosetting resin composition.
