To improve the production yield of emulsion containing seamless capsule by discharging an emulsion containing dispersing elements, of which the average particle diameter is a specified value, from the inside nozzle of multiple nozzles, of which the diameters are successively increased, discharging liquid for film formation from the outside nozzle, forming multilayer liquid drops and hardening them.
While using the multiple nozzles such as triple nozzles, for example, of which the diameters are successively increased, the liquid for film formation is supplied and discharged to an inlet 4 of an outer-most nozzle 3. An oil component is supplied and discharged from an inlet 5 of an intermediate nozzle 2 and emulsion containing liquid is supplied and discharged from an inlet 6 of an inner-most nozzle 1 respectively so that the multilayer liquid drops can be formed. These drops are hardened into the emulsion containing seamless capsule. The emulsion is formed by dispersing the dispersing element, of which the average particle diameter is smaller than 10μm, into an anionic surface-active agent, etc. A film forming object is not specially limited when it is a material to be hardened or gelled by a means such as cooling.
