Claims9
A ceramic joint body comprising:
- a plurality of ceramic substrates overlapping along a thickness direction to comprise a channel inside, the plurality of ceramic substrates being diffusion bonded to each other at opposing surfaces, wherein
- the plurality of ceramic substrates each comprise aluminum oxide as a main constituent, and each comprise from 0.02 mass % to 10 mass % of silicon in terms of oxide,
- the plurality of ceramic substrates include at least three ceramic substrates that overlap along the thickness direction, and
- end portion sides of the ceramic substrates located on both sides in the thickness direction each comprise less silicon in terms of oxide than the ceramic substrate sandwiched between the ceramic substrates located on both sides.
