摘要

There is provided a bonded article obtained by unitarily bonding two or more target articles to be bonded by means of a bonding material layer. The bonding material layer contains layer silicate, and the average linear thermal expansion coefficient ± 1000°C specified by the following formula (1) and the average linear thermal expansion coefficient ± 400°C specified by the following formula (2) of a test piece cut out from the bonding material layer satisfy the following formula (3): ± 1000°C = (l 1000°C - l 40°C ) / {l 40°C × (1273.15K - 313.15K)} (1) (where, l 1000°C represents length of the test piece at 1000°C, and l 40°C represents length of the test piece at 40°C), ± 400°C = (l 400°C - l 40°C ) / {l 40°C × (673.15K - 313.15K) } (2) (where, l 400°C represents length of the test piece at 400°C, and l 40°C represents length of the test piece at 40°C), |± 1000°C -± 400°C l ‰¤2.0×10 -6 /K (3).
