The present invention provide it is a kind of without using organic solvent and regardless of the type of core material, be readily available the universe it is dry under excellent storage stability using carboxymethyl cellulose as the manufacturing method of the microcapsules of membranous wall. It is set as the manufacturing method of following microcapsules,The characteristic of the manufacturing method of the microcapsules is the step of what includes: to mix with more than one water soluble polymer in addition to this in turn and prepare aqueous solution carboxymethyl cellulose and/or its sodium salt； Into the aqueous solution be added by the viscosity at resulting 25 DEG C of Type B viscosmeter be the mPas of 100 mPas~10000 lyophobic dust or hydrophobicity constituent,Or by be the mPas of 100 mPas~10000 by the viscosity at resulting 25 DEG C of Type B viscosmeter lyophobic dust or hydrophobicity constituent and fusing point be 25 DEG C~80 DEG C lyophobic dust melting mixing made of mixture and the step of prepare emulsified suspension； And the step of metal salt of divalent or more is added into the emulsified suspension.本發明提供一種不使用有機溶媒且無論芯物質的種類如何，容易地獲得乾燥下的保存穩定性優異的將羧甲基纖維素作為膜壁的微膠囊的製造方法。設為如下的微膠囊的製造方法，所述微膠囊的製造方法的特徵在於包括：將羧甲基纖維素及/或其鈉鹽進而與一種以上的除此以外的水溶性高分子混合而製備水溶液的步驟；向所述水溶液中加入藉由B型黏度計所得的25℃下的黏度為100 mPa·s～10000 mPa·s的疏水性物質或疏水性組成物、或者將藉由B型黏度計所得的25℃下的黏度為100 mPa·s～10000 mPa·s的疏水性物質或疏水性組成物與熔點為25℃～80℃的疏水性物質熔融混合而成的混合物而製備乳化懸浮液的步驟；以及向所述乳化懸浮液中添加二價以上的金屬鹽的步驟。
