PURPOSE:To make a ceramic thin sheet applicable under the high temperature environment of more than a temperature of 900 deg.C, by joining plural ceramic thin sheets consisting of silicon nitride, silicon carbide, etc., with a ceramic bonding material composed of te same type component as this thin sheet. CONSTITUTION:A doughnut plate type ceramic thin sheet 1 provided with a round hole in the almost nearly central part is superposingly set up in bellows form via a spacer 2 so as to cause end edge parts themselves at both inner and outer circumferential sides of two ceramic thin sheet surfaces adjoined with each other to be alternately joined in succession. A contact surface between the ceramic thin sheet 1 and the spacer 2 is joined together with a ceramic bonding material 3. As for the ceramic thin sheet 1, for example, those of silicon carbide, silicon nitride, cyaron, etc., are suitable. The ceramic bonding material 3 consists in the same or similar component as the main component of the ceramic thin sheet 1. |
