PROBLEM TO BE SOLVED: To prepare a good porous particle. SOLUTION: A primary emulsion 14 comprising a first dispersed phase 13 dispersed in a first continuous phase 11 contg. a solidifiable component is prepd. This primary emulsion 14 is dispersed as a second dispersed phase 15 in a second continuous phase 16 to prepare a secondary emulsion 17. In this state, the solidifiable component is solidified, and, thereafter, the first dispersed phase portion of the primary emulsion 14 is removed to form a porous particle with a pore 18 provided by removal of the first dispersed phase 13. |
