多孔質体、放熱構造体及び電子機器
Document Type and Number:
Japanese Patent JP7231121
Kind Code:
B2
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).
