The present invention provides, for example, a silicone porous body having a porous structure with less cracks and a high proportion of void space as well as having a strength. The silicone porous body of the present invention includes silicon compound microporous particles, wherein the silicon compound microporous particles are chemically bonded by catalysis. For example, the abrasion resistance measured with BEMCOT® is in the range from 60% to 100%, and the folding endurance measured by the MIT test is 100 times or more. The silicone porous body can be produced, for example, by forming the precursor of the silicone porous body using sol containing pulverized products of a gelled silicon compound and then chemically bonding the pulverized products contained in the precursor of the silicone porous body. The chemical bond among the pulverized products is preferably a chemical crosslinking bond among the pulverized products, for example.
