PROBLEM TO BE SOLVED: To provide a method for producing particles, capable of efficiently producing the particles having high stability, by using an unstable compound as a raw material powder. SOLUTION: This method for producing the particles particles comprises adding a binder solution which is formed by dissolving, dispersing, or suspending the compound in a solvent to a powder of the compound, while the powder is moved in a treating container, so that granular particles are produced, wherein the compound comprises a compound which produces chemical or physical interaction with another substance, such as a non-crystalline compound and an amorphous compound, when mixed therewith, becomes unstable, and easily causes degeneration (such as decomposition and degeneration, dissolution and migration, decrease in contents, and deterioration in storage stability and light stability).
