PROBLEM TO BE SOLVED: To provide an inorganic/organic composite nanosheet and a method for producing the same, and to provide a method for swelling a layered silicon compound/organic composite in which an inorganic part and an organic part are bonded by a covalent bond. SOLUTION: The inorganic/organic composite nanosheet has such a sheet-like shape that the length of two sides among three sides are 0.1-2μm respectively, the length of other side is 1-3 nm, and the thickness is of a nanometerorder, includes the inorganic part and the organic part bonded by the covalent bond, and is expressed by general formula: R<SB>h</SB>M<SB>6/i</SB>Si<SB>j</SB>O<SB>k</SB>(OH)<SB>l</SB>(wherein, R is an organic group; M is at least one kind of element selected from Mg, Al, and Fe; 0.1≤h≤1; i is valence of the element M; 2≤j≤4; 6≤k≤10; and 2≤l≤6). The inorganic part has a structure similar to a 2:1-type layered clay mineral, in which the elements M form an octahedral sheet which is sandwiched by two tetrahedral sheets formed of Si.
