PROBLEM TO BE SOLVED: To provide particles containing a poorly water-soluble substance having excellent elution property of the poorly water-soluble substance and fluidity of the particles. SOLUTION: The following components (A), (B) and (C): (A) gelatin, (B) poorly water-soluble substance, and (C) (c1) constituent fatty acids are saturated fatty acids having 8 to 14 carbon atoms. Monoglycerin fatty acid ester, (c2) polyglycerin fatty acid ester, (c3) glycerin acetic acid fatty acid ester, (c4) propylene glycol fatty acid ester in which constituent fatty acids are saturated fatty acids having 8 to 14 carbon atoms, and (c5) sucrose fatty acid ester. Water-insoluble substance-containing particles containing one or more selected from the group, a continuous phase containing the component (A), and a dispersed phase containing the component (B) dispersed in the continuous phase. Water-soluble substance-containing particles having.
