Zinc oxide-containing composite particles of the present invention each include: a dense matrix formed of silica and a polysilsesquioxane; and zinc oxide particles dispersed within the matrix. The content of the polysilsesquioxane in the matrix is 30 mass% to 70 mass%. The zinc oxide-containing composite particles of the present invention have high acid resistance and are capable of maintaining acid resistance even upon contact with water.
