摘要： Disclosed are a ceramics sheet which has an area of 400 cm² or more, thickness of 0.4 mm or less, maximum waviness height of 100 µm or less, and warp of 0.1 % or less and in which frequency of generated cracking and breakage is 10% or less when a load-applying test and a deflection-loading test each described in the text are carried out in succession, and a flat and large ceramics sheet having an area of 600 cm² or more and thickness of 1 mm or less. Further, disclosed is a method for producing a ceramics sheet having the characteristics described above and characterized in that in calcining a ceramics green sheet to produce a ceramics sheet, the green sheet described above is interposed between porous sheets which have bulk density corresponding to 30 to 85 % of the theoretical density and in which the shrinkage rate caused by heating up to the calcining temperature of the above green sheet is 5 % or less on condition that the periphery of the green sheet does not protrude from the porous sheets, and calcined.
