摘要:
An object of the invention is to provide a flat ceramic sheet including an internal electrode used for manufacturing a multilayer ceramic electronic part. Specifically, an electrode portion is formed on a surface of a transparent base member, and a photosensitive slurry containing dielectric powder is applied thereon. The photosensitive slurry is exposed from the backside of the base member up to a predetermined thickness, and then it is subjected to development. After that, the base member is removed. Thus, a ceramic green sheet is obtained.

The invention relates to a so-called ceramic green sheet used for manufacturing multilayer ceramic electronic parts. The invention is intended to improve accuracy in shape of an electrode or other element formed on the sheet, accuracy in its position and uniformity in its thickness. In a process according to the invention, a layer made of a photosensitive material including a powder having a desired electric characteristic is formed on a light transmissive base member. A mask having a desired pattern is disposed on the back side of the base member and the photosensitive material is exposed from the back side of the base member through the mask. Then the photosensitive layer after the exposure is subjected to development.
