It is possible, to obtain the micro capsule whose grain diameter is small sufficiently in order the first fog condition fluid of the thin film condition which includes the first liquid drop where recovery is high in the small space, contains the gel formation material and the lipophilicity material and the second fog condition fluid of the thin film condition which includes the second liquid drop which contains the gelatinizer, to cross mutually in the vapor phase, making collide, production manner of the micro capsule where mean particle diameter obtains the micro capsule of 100 millimicrons or less.粒子径が十分に小さいマイクロカプセルを得ることが可能であり、小スペースで回収率が高く、ゲル形成物質及び脂溶性物質を含有する第一の液滴を含む薄膜状の第一の霧状流体と、ゲル化剤を含有する第二の液滴を含む薄膜状の第二の霧状流体とを、気相中で相互に交差するように衝突させて、平均粒子径が100μm以下のマイクロカプセルを得るマイクロカプセルの製造方法。
