Abstract
A plurality of insertion holes for inserting one end of each of a plurality of cells is formed on the surface of a support substrate. One end of each of the cells is loosely fitted in the corresponding insertion hole. A joining material is provided so as to fill at least a gap present between the inner wall of the insertion hole and the outer wall of the one end of the cell in each joining portion between each of the insertion holes and one end of the corresponding cell. As the joining material, crystallized glass which includes a plurality of kinds of crystal phases generated when the crystallization of amorphous glass heated up to a crystallization temperature proceeds is used, and a volume reduction ratio (crystallization shrinkage ratio) of the joining material caused by the crystallization at the crystallization temperature is 0.78% or more and 12% or less.
