Abstract

　単分散の磁性体微粒子が作成出来、自己排出性により生成物の詰まりも無く、大きな圧力を必要とせず、生産性も高い、磁性体微粒子の製造方法を提供することを課題とするものであって、少なくとも２種類の流体を用いるものであり、そのうちで少なくとも１種類の流体については、磁性体原料を少なくとも１種類含むものであり、上記以外の流体のうちで少なくとも１種類の流体については、磁性体微粒子析出剤を少なくとも１種類含むものであり、近接・離反可能に互いに対向して配設され、少なくとも一方が他方に対して回転する処理用面の間にできる薄膜流体中で上記の各流体を合流させ、前記薄膜流体中で磁性体微粒子を析出させて磁性体微粒子を得る。
