Document Type and Number:
WIPO Patent Application WO/2024/090364
Kind Code:
A1
Abstract:
[Problem] To provide a multilayer body which has excellent heat dissipation performance in the thickness direction, excellent thermal diffusibility in the in-plane direction, and excellent electrical insulation performance in the thickness direction, and which is not susceptible to cracking. [Solution] Disclosed is a multilayer body which comprises a metal layer A, an insulating layer that is provided on at least one surface of the metal layer A, and a metal layer B that is provided on a surface of the insulating layer, the surface being on the reverse side from the metal layer A. This multilayer body is characterized in that: the insulating layer comprises a supporting layer and a heat transfer layer that contains at least an inorganic filler and a binder resin; and the supporting layer and the heat transfer layer are alternately stacked in a direction that is generally perpendicular to the thickness direction of the insulating layer so that the total number of layers is 3 or more.
