Title:
POROUS BODY, HEAT-DISSIPATING STRUCTURE, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/075172
Kind Code:
A1
Abstract:
Provided is a porous body that allows a fluid, e.g., a liquid, to move from one surface to another surface and can hold and store a large amount of the fluid. This porous body (10) has a first principal surface (11), a second principal surface (12) that is opposite the first principal surface (11), and a plurality of pores (20). At least a portion of the pores (20) are connecting pores (21) that connect the first principal surface (11) and the second principal surface (12). When a first cross-section (CS1) is taken by bisecting the porous body (10) perpendicularly to the direction from the first principal surface (11) to the second principal surface (12), the porosity of the first principal surface (11) is less than the porosity of the first cross-section (CS1), and the porosity of the second principal surface (12) is also less than the porosity of the first cross-section (CS1).
