Provided is a production method capable of obtaining composite particles with less aggregation of composite particles by a simplified production process without using an organic solvent harmful to the human body or performing heat treatment. The task is to In the present invention, composite particles are obtained by this production method. In a supercritical fluid or a subcritical fluid, a particle A is contacted with a particle B having an average particle diameter of 1/5 or less of the average particle diameter of the particle A and an organic compound. A method for producing a composite particle in which a particle B and an organic compound are present on the surface of a particle A for removing a critical fluid or a subcritical fluid, and in the presence of a supercritical fluid or a subcritical fluid, the particles and the surface of the particle. A method for producing composite particles, wherein a supercritical fluid or a subcritical fluid is removed after the substance having an adsorption ability is brought into contact with a substance having an adsorption ability on the surface of the particles, and the production method The composite particles obtained in the above.
