A method for producing hollow silica particles, which comprises: adjusting the pH of an oil-in-water emulsion containing an aqueous phase, an oil phase and a surfactant to at most 3.0 and adding a first silica material to the oil-in-water emulsion, adding a second silica material to the emulsion having the first silica material added, at its pH of at least 8, in the presence of alkali metal ions, to obtain a hollow silica precursor dispersion, and obtaining a hollow silica precursor from the hollow silica precursor dispersion and obtaining hollow silica particles from the hollow silica precursor, wherein the hollow silica precursor is in the form of oil core/silica shell particles, the first silica material and the second silica material are each independently an aqueous solution having water-soluble silica dissolved, an aqueous dispersion having solid silica dispersed, a mixture thereof, or at least one member selected from the group consisting of an alkali metal silicate, activated silicic acid and a silicon alkoxide, or an aqueous solution or aqueous dispersion thereof, wherein the activated silicic acid is one obtained by subjecting an alkali metal silicate to cation exchange to replace the alkali metal with hydrogen, the second silica material is added to the heated emulsion, wherein the heating temperature is from 30 to 100°C, the method of obtaining the hollow silica precursor from the hollow silica precursor dispersion is selected from a method of subjecting the dispersion to filtration, a method of removing the aqueous phase by heating, or a method of separating the precursor by sedimentation or centrifugal separation, and a method of removing the oil core from the hollow silica precursor to obtain hollow silica particles is selected from a method of baking the hollow silica precursor so that the oil is burnt and decomposed, a method of volatilizing the oil by drying, a method of adding an appropriate additive to decompose the oil, or a method of extracting the oil. adjusting the pH of an oil-in-water emulsion containing an aqueous phase, an oil phase and a surfactant to at most 3.0 and adding a first silica material to the oil-in-water emulsion, adding a second silica material to the emulsion having the first silica material added, at its pH of at least 8, in the presence of alkali metal ions, to obtain a hollow silica precursor dispersion, and obtaining a hollow silica precursor from the hollow silica precursor dispersion and obtaining hollow silica particles from the hollow silica precursor, wherein the hollow silica precursor is in the form of oil core/silica shell particles, the first silica material and the second silica material are each independently an aqueous solution having water-soluble silica dissolved, an aqueous dispersion having solid silica dispersed, a mixture thereof, or at least one member selected from the group consisting of an alkali metal silicate, activated silicic acid and a silicon alkoxide, or an aqueous solution or aqueous dispersion thereof, wherein the activated silicic acid is one obtained by subjecting an alkali metal silicate to cation exchange to replace the alkali metal with hydrogen, the second silica material is added to the heated emulsion, wherein the heating temperature is from 30 to 100°C, the method of obtaining the hollow silica precursor from the hollow silica precursor dispersion is selected from a method of subjecting the dispersion to filtration, a method of removing the aqueous phase by heating, or a method of separating the precursor by sedimentation or centrifugal separation, and a method of removing the oil core from the hollow silica precursor to obtain hollow silica particles is selected from a method of baking the hollow silica precursor so that the oil is burnt and decomposed, a method of volatilizing the oil by drying, a method of adding an appropriate additive to decompose the oil, or a method of extracting the oil. <EOS>
