Title:
INSULATING SHEET AND POWER SUPPLY DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/256093
Kind Code:
A1
Abstract:
Provided is an insulating sheet for which insulation performance is maintained while manufacturing costs are lowered. An insulating sheet (10) comprises a middle layer (11) and surface layers (12) layered on surfaces of the middle layer (11). The surface layers (12) have a heat conductivity of 0.50 W/m∙K or less in the direction of thickness, and the middle layer (11) has a heat conductivity of 1.00 W/m∙K or more in the direction of thickness. The pore diameter of the surface layers (12) may be 50 µm or less. This configuration imparts insulating properties to the surface layers (12) and consequently prevents fire from spreading, and eliminates the need to seal the surface layers (12), thus making it possible to provide the advantageous feature of being able to carry out production with ease and at a low cost.
