(57) [Problem] To provide a method for producing polyimide fine particles capable of controlling the particle shape, particle size distribution, and the like. Also provided are polyamic acid fine particles and polyimide fine particles having excellent monodispersibility. In a method for synthesizing a polyimide from a tetracarboxylic anhydride and a diamine compound, (a) a first step of preparing a first solution containing a tetracarboxylic anhydride and a second solution containing a diamine compound, respectively, b) mixing the first solution and the second solution, a second step of precipitating polyamic acid fine particles from the mixed solution, and (c) a third step of obtaining polyimide fine particles by imidizing the obtained polyamic acid fine particles A method for producing polyimide fine particles, comprising: |
