摘要： Provided is an inorganic structure (1, 1A) including a plurality of magnesium oxide particles (2); and a binding part (3) that covers a surface of each of the magnesium oxide particles (2) and binds the magnesium oxide particles (2) together. The binding part (3) contains an amorphous compound containing silicon, a metallic element other than silicon, and oxygen, and contains substantially no alkali metal, B, V, Te, P, Bi, Pb, and Zn. Also provided is a method for producing an inorganic structure (1, 1A) including: a step for obtaining a mixture by mixing a plurality of magnesium oxide particles (11), a plurality of amorphous silicon dioxide particles (12), and an aqueous solution (13) containing a metallic element other than silicon; and a step for pressurizing and heating the mixture under conditions of a pressure of 10 to 600 MPa and a temperature of 50 to 300 °C.
