INSULATING STRUCTURE AND METHOD FOR MANUFACTURING SAME

摘要

Provided is an insulating heat conductive structure having excellent heat conductivity and stability to thermal deformation due to temperature cycle and the like. In a method for manufacturing the insulating heat conductive structure, an insulating layer and a circuit layer are provided in this order from the side of a metal base material at least on a part of the surface of the metal base material, and the insulating layer is formed of a composite phase composed of a ceramic phase and a resin phase. On the cross-section of the insulating layer, the ceramic phase composed of a large number of deposited ceramic particles is formed in a plurality of independent patterns and in a state where a part of the ceramic phase is embedded in the metal base material and the circuit layer, and the spaces between the ceramic phases are filled with the resin phase.
