PROBLEM TO BE SOLVED: To provide a method for producing a composite particle by agitating a raw material powder of a specific shape and a polymer in the presence of carbon dioxide.
SOLUTION: This method for producing the composite particle includes at least: a filling step of filling a raw material which contains the polymer and the raw material powder having an internal friction angle of &ge20° and an agitating step of agitating the raw material filled in the filling step, in a container in the presence of the carbon dioxide of &ge2 MPa. In the method, the carbon dioxide is introduced by at least one introducing step selected from the group consisting of: (i) a step introduced so that pressure in the container increases at a rate of &le0.7 MPa/min, after the filling step and/or during the agitating step (ii) a step introduced from a side or a bottom of the container, after the filling step and/or during the agitating step and (iii) a step introduced under agitation with the raw material, during the agitating step.
