Abstract: A nitride-based ceramics resin composite body having thermal conductivity, electrical insulation, and adhesion to adherends equal to conventional products, and having improved heat resistance reliability during the reflow process, and a thermal conductive insulating adhesive sheet using the same are provided. A nitride-based ceramics resin composite body in which a thermosetting resin composition is impregnated in a porous nitride-based ceramics sintered body is provided. The thermosetting resin composition includes a specific epoxy resin and a bismaleimide triazine resin, and a water absorption of the thermosetting resin composition in a completely cured state measured in accordance with method A in JIS K7209 (2000) is 1% by mass or less.

Abstract: A ceramic-metal temporary bonding body to inhibit breakage and degradation of a ceramic resin composite having low strength includes: a ceramic resin composite in which a non-oxide ceramic sintered body is impregnated with a thermosetting resin composition having cyanate groups in such a manner that a degree of cure calculated by differential scanning calorimetry is 5.0% or more and 70% or less; and a metal plate temporarily bonded to at least one surface of the ceramic resin composite. A shear bond strength between the ceramic resin composite and the metal plate is 0.1 MPa or more and 1.0 MPa or less.
