Abstract
A ceramic green sheet is manufactured by preparing a support which includes a releasing layer formed on its top surface and has a smoothness that at least a region of the top surface of the support to be coated with a ceramic slurry has substantially no projections having a height of equal to or more than about 1 μm, and applying a ceramic slurry to the releasing layer of the support, which ceramic slurry contains a ceramic powder dispersed in a medium. This ceramic green sheet has a small thickness of, for example, about 0.3 to 3 μm, has no depressions or through holes caused by a filler in the support and is excellent in smoothness.

A method for manufacturing a ceramic green sheet for multilayer ceramic electronic parts by applying a ceramic slurry onto a support, the method comprising:
- providing a support having top and bottom surfaces and having a releasing layer on its top surface and having a smoothness such that at least a region of the top surface of the support to be coated with a ceramic slurry has substantially no projections having a height of equal to or more than about 1 μm;
- and
- applying a ceramic slurry comprising a ceramic powder dispersed in a medium to the releasing layer of the support.
