PROBLEM TO BE SOLVED: To provide a joining material capable of minimize residual stress after joining regardless of an application temperature or kinds of a low expansion material to be joined.SOLUTION: A joining material contains a crystalline glass depositing 20 to 70 mass% of a LiO-AlO-SiO-based crystal and 1 to 75 mass% of a RO-AlO-SiO-based crystal (R=Mg, Ca, Sr, Ba) or a R'O-AlO-SiO-based crystal (R'=Na, K) by a heating treatment. |
