摘要：<P>PROBLEM TO BE SOLVED: To provide a sheet like ceramic with reduced waste ratio of a material, a uniform thickness and decreased defects and a method of manufacturing the same. <P>SOLUTION: The sheet like ceramic is manufactured by spreading a ceramic slurry composition containing a water soluble binder, ceramic powder and water and having ≥2% to <5% solid ratio by volume on a supporting body to form a sheet of the ceramic slurry and drying, degreasing and firing the sheet. As the ceramic powder, ceramic dielectric powder consisting essentially of lead titanate zirconate is used and the thickness of the ceramic slurry composition after being dried, that is the green sheet, is controlled to ≥200 μm to ≤270 μm. The thickness of the sheet like ceramic obtained after being fired is controlled to ≥140 μm to ≤270 μm. <P>COPYRIGHT: (C)2005,JPO&NCIPI
