ABSTRACT:
A method for manufacturing a multilayer ceramic electronic component can prevent the occurrence of bubble trapping. In the method, when an external layer ceramic green sheet is pressure-bonded, for example, to a sheet made of a good quality paper having a rough surface, which is placed on a supporting member, followed by peeling off its carrier film, a first-layer ceramic green sheet is formed. The first-layer external layer ceramic green sheet uses a sterically hindered dispersing agent, such as an aryl ether polymer, as a dispersing agent. Since it is light in weight, the binder segregates at the upper side, and hence a C concentration changes in the thickness direction. More particularly, compared to a C concentration at a surface at a carrier film side supported by the carrier film, a C concentration at an open surface opposite to the surface at the carrier film side is about 1.5 to about 4.0 times.
