PROBLEM TO BE SOLVED: To provide a porous silicone body that forms a porous structure with a high porosity while suppressing the occurrence of cracks and has strength. The silicone porous body of the present invention includes fine pore particles of a silicon compound, and the fine pore particles of the silicon compound are chemically bonded to each other through a catalytic action. The silicone porous body of the present invention has, for example, a scratch resistance of 60-100% by Bencot (registered trademark) and a folding resistance of 100 or more by the MIT test. The silicone porous body is formed by, for example, forming a precursor of the silicone porous body using a sol containing a pulverized product of a gel-like silicon compound, and chemically treating the pulverized products contained in the precursor of the silicone porous body. It can manufacture by combining with. The chemical bond between the pulverized products is preferably, for example, a chemical cross-linking bond between the pulverized products.
