Abstract: The present invention relates to a method of producing oil-containing silica capsule particles having a core containing an oil and a shell containing silica as a constitutional component, including: step 1: a step of emulsifying an oil mixture liquid containing a surfactant, water, an oil, and a silica precursor, with an in-line emulsifier/disperser, so as to provide an emulsion liquid; and step 2: a step of forming oil-containing silica capsule particles by using the emulsion liquid obtained in the step 1, in a batch type agitation tank.
