Inorganic structure and method for producing same

An inorganic structure, comprising:

• a plurality of inorganic particles;
• and
• a binding part that covers a surface of each of the plurality of inorganic particles and binds each of the plurality of inorganic particles together, wherein
• the binding part contains:
• an amorphous compound containing at least one of aluminum or titanium, oxygen, and one or more metallic elements;
• and a plurality of fine particles having an average particle size of 100 nm or less,
• the plurality of inorganic particles has an average particle size of 1 μm or more,
• the plurality of inorganic particles has a volume percentage of 30% or more, and
• an inorganic substance constituting the inorganic particles is at least one selected from the group consisting of an oxide of a metallic element, a nitride of a metallic element, a hydroxide of a metallic element, an oxide hydroxide of a metallic element, a sulfide of a metallic element, a boride of a metallic element, a carbide of a metallic element, and a halide of a metallic element.
