Provided is a method for manufacturing stacked ceramic electronic components, which provides superior mounting stability and prevents the generation of delamination of an internal electrode and a ceramic layer. The method includes a process of preparing the first ceramic outer layer (7) of a mother, stacking internal electrodes (5) and the ceramic green sheets (8) of the mothers on the first ceramic outer layer (7) of the mother, and performing a first press in a stacking direction after the ceramic inside outer layer (9) of the mother is formed, a process of forming the outside outer layer of the mother on the ceramic inside outer layer (9) of the mother and performing a second press in a stacking direction after the second ceramic outer layer of the mother is formed, and forming the laminate of the mother, a process of cutting the laminate of the mother and obtaining each laminate, a process of sintering each of the laminates and obtaining a ceramic body, and a process of forming a first and a second external electrode on the outer surface of the ceramic body. 내부전극과 세라믹층의 디라미네이션이 발생하기 어려우면서, 실장 안정성이 뛰어난 적층 세라믹 전자부품의 제조방법을 제공한다. 마더의 제1의 세라믹 외층(7)을 준비하고, 상기 마더의 제1의 세라믹 외층(7)상에 복수의 내부전극(5)과, 복수장의 마더의 세라믹 그린시트(8)를 적층하며, 또한 마더의 세라믹 내측 외층(9)을 형성한 후, 적층방향으로 제1의 프레스를 실시하는 공정과, 상기 마더의 세라믹 내측 외층(9)상에, 마더의 세라믹 외측 외층을 형성하여, 마더의 제2의 세라믹 외층을 형성한 후, 적층방향으로 제2의 프레스를 실시함으로써, 마더의 적층체를 형성하는 공정과, 상기 마더의 적층체를 컷트하여, 개개의 적층체를 얻는 공정과, 상기 개개의 적층체를 소결하여, 세라믹체를 얻는 공정과, 상기 세라믹체의 외표면에 제1, 제2의 외부전극을 형성하는 공정을 포함하는 적층 세라믹 전자부품의 제조방법.
