In a method for finely pulverizing an organic compound 5 in treatment target liquid 2 to manufacture fine particles of the organic compound 5 , a laser beam having a wavelength which is longer than the light absorption band of the organic compound 5 or corresponds to an absorption wavelength of solvent is irradiated to the treatment target liquid 2 to finely pulverize the organic compound 5 , thereby manufacturing fine particles of the organic compound 5 . According to this manufacturing method, the fine particles can be manufactured with sufficiently preventing photochemical reactions of the organic compound 5 in the treatment target liquid 2 . Accordingly, a fine particle manufacturing method and apparatus that can manufacture fine particles while sufficiently preventing photochemical reactions in the organic compound, fine particles, and injectable agent and a manufacturing method for the injectable agent can be implemented. |
