ク基板４０枚を得た。Example 2 parts of talc were added to 98 parts by weight of alumina (hereinafter simply referred to as "parts") having an average particle size of 2.8 croms, mixed, 5 parts of methylcellulose and a portion of water were added, kneaded, formed into a sheet with a thickness of 1.1 ff, and dried. After that, put a cross-shaped dotted line in the center of the 800 x 800 fi size, and the finished size is 400 x 40.
Ten Ceramiwak green sheets obtained by punching to obtain four ceramic substrates of 0 mm size were placed on an alumina setter, and the temperature was raised to 1570 °C at a temperature increase rate of 100 °C / hour. After firing at 1570° C. for 3 hours, the temperature was lowered and airplast cleaning was performed to remove foreign matter, and the substrate was divided into four pieces along the dotted line to obtain 40 ceramic substrates of 400 x 400 fl.
