To provide a ceramic sheet capable of improving impact resistance and durability while ensuring flexibility, an antenna apparatus, a wireless communication medium processing apparatus and a manufacturing method of the ceramic sheet.
In the method, at least one of blocks 15 keeps contact with a sheet 13b at a contact face 11a and at the same time faces the other block adjoined at an opposite face 11b, on the other hand, as it has a non-contact face 12 which does not come to contact with the other block 15 each other between the contact face 11a and the opposite face 11b, when the ceramic sheet 10 is bent, blocks 15 adjoined to each other so that stress can not be concentrated between the contact face 11a and the opposite face 11b. Thereby, even though the ceramic sheet 10 receives external stress or shock, the block 15 can be kept not to be easily destroyed.
