Document Type and Number:
WIPO Patent Application WO/2018/012445
Kind Code:
A1
Abstract:
The objective of the present invention is to provide: a metal-clad laminate which has excellent heat dissipation properties and flexibility, and wherein an insulating layer comprises a graphite sheet as a heat dissipation material and is capable of suppressing breakage of the graphite sheet; and a printed wiring board. A metal-clad laminate (1) according to the present invention is provided with a conductor layer (10) and an insulating layer (20) that is superposed on the conductor layer (10). The insulating layer (20) comprises a base material (21) having electrical insulation properties and a graphite sheet (22) which is embedded in the base material (21). The insulating layer (20) has a thermal conductivity of 100 W/m·K or more. This metal-clad laminate (1) has a folding endurance of 3 folds or more as evaluated by a folding endurance test with a curvature radius of 3 mm.
