To provide a grinding method of a porous body containing hydrophilic macromolecule, capable of suppressing occurrence of charring; and to provide a production method of a ground product in which occurrence of charring is suppressed.SOLUTION: In a grinding method of a porous body, including grinding of the porous body containing hydrophilic macromolecule, a moisture content of the porous body before grinding is 13.5 mass% or less, and the method of grinding is dry grinding. A production method of a ground product includes steps of: adjusting the moisture content of the porous body containing hydrophilic macromolecule at 13.5 mass% or less: and grinding the porous body by dry grinding.SELECTED DRAWING: Figure 1 【課題】焦げの発生を抑制できる、親水性高分子を含む多孔質体の粉砕方法、及び焦げの発生の抑制された粉砕物の製造方法を提供する。【解決手段】親水性高分子を含む多孔質体を粉砕することを含み、粉砕前の多孔質体の含水率は１３．５質量％以下であり、粉砕の方式は乾式粉砕である、多孔質体の粉砕方法、及び、親水性高分子を含む多孔質体の含水率を１３．５質量％以下とする工程と、乾式粉砕により多孔質体を粉砕する工程と、を含む粉砕物の製造方法。【選択図】図１
