The present invention develops a method for producing embedded particles of chemical substances suitable for shortening the production process, reducing the production cost, and suitable for mass production of particles. A nozzle in a duct includes a step of melting a base material, a step of uniformly mixing the molten base material and a chemical substance embedding material, and a mixture of the melted base material and the chemical substance embedding material. Accordingly, it maintained at least 5 ° C. or more lower than the melting point of the base material, the method for producing particles and a step of specific gravity is injected into the medium solution is 0.6g / cm 3 ~1.5g / cm 3 , blended A chemical substance embedding particle comprising a base material having an amount of 30 to 99.9% by weight and a chemical substance embedding material having a blending amount of 0.1 to 70% by weight is manufactured.
