Abstract
There is provided a constraining green including a first constraining layer having a surface disposed on the one of the top and bottom surfaces of the ceramic laminated body, the first constraining layer containing a first inorganic powder; and a second constraining layer disposed on a top of the first constraining layer and containing a second inorganic powder and a fly ash. The constraining green sheet serves to ensure less shrinkage of the ceramic laminated body and improve debinding characteristics.
