pressing said composite laminate in the laminating direction; and
sintering said composite laminate;
wherein one of said shrinkage-suppressing layers which is formed over the surface in which said open surface of said cavity is provided is formed so as to have a second opening for exposing said open surface of said cavity at the step of obtaining said composite laminate, and at the step of pressing said composite laminate, the bottom portion of said cavity is pressed via said second opening while the surrounding region of the cavity is pressed.
2. The method according to claim 1, wherein said second opening has substantially the same shape as said open surface of said cavity.
3. The method according to claim 2, wherein said second glass-ceramic sheets are not provided with openings.
4. The method according to claim 1, wherein, during the step of pressing said composite laminate, said composite laminate is pressed in the laminating direction in a manner such that the bottom portion of said cavity receives the same amount of pressure as the surrounding region of said cavity.
5. The method according to claim 1, wherein said composite laminate is not pressed in the laminating direction during the step of sintering said composite laminate.
6. The method according to claim 1, further comprising the step of removing said shrinkage-suppressing layers after the step of sintering said composite laminate.
7. The method according to claim 1, further comprising the step of mixing the low-sintering-temperature ceramic material with an organic component for obtaining a desired slurry, and using the slurry to form the first glass-ceramic green sheets and the second glass-ceramic green sheets.
