Abstract

An intermediate member is a member which is directly or indirectly sandwiched between a first object and a second object. The intermediate member includes a plate-like supporting member having a lower surface which is one main surface opposed to the first object and a plurality of ceramic blocks fixed on an upper surface which is the other main surface of the supporting member in a state of being separated from one another. Thus, in a state where the plurality of ceramic blocks are collectively held by the supporting member having relatively high shape retention, by disposing the intermediate member between the objects, it is possible to easily arrange the plurality of ceramic blocks between the objects with high positioning accuracy.

First claim

The invention claimed is:

1. An intermediate member which is sandwiched between a first object and a second object, comprising:
a plate-like supporting member having two main surfaces, with a first main surface opposed to said first object; and
a plurality of ceramic blocks fixed on a second main surface of said supporting member in a state of being separated from one another,
wherein a porosity of said plurality of said ceramic blocks is not lower than 20% and not higher than 80%,
said supporting member is formed of a metal,
said supporting member has a thickness that is not smaller that 0.02 mm and not larger than 3 mm,
said plurality of ceramic blocks are adhered onto said supporting member with an adhesive agent, and
an adhesive strength between said plurality of ceramic blocks to said supporting member is not lower than 0.1 MPa and not higher than 10 MPa.

2. The intermediate member according to claim 1 , wherein
said plurality of ceramic blocks have a thickness that is not less than twice and not more than 100 times that of said supporting member.

3. The intermediate member according to claim 1 , wherein
said plurality of ceramic blocks have a thickness that is not smaller than 0.04 mm and not larger than 300 mm.

4. The intermediate member according to claim 1 , further comprising:
another plate-like supporting member which includes two main surfaces, with a first main surface that is opposed to said second object and said plurality of ceramic blocks are fixed on a second main surface.
