CERAMIC BONDED BODY
A ceramic bonded body of the present disclosure includes a first member, a second member, a joining layer between the first member and the second member, and a covering layer which covers the joining layer and is located over the first member and the second member. The first member and the second member are comprised of aluminum nitride-based ceramic. The joining layer and the covering layer contain at least aluminum, calcium, yttrium, and oxygen where, in 100 mass% of all of the constituents configuring the joining layer and the covering layer, the aluminum is 21 mass% or more converted to oxides, the calcium is 21 mass% or more converted to oxides, and the sum of the aluminum and the calcium converted to oxides is 86 mass% or more. The covering layer has a content of yttrium converted to oxides larger than that of the joining layer.
