ABSTRACT:
In order to improve the reliability of a glass joint body, a first ceramic member and a second ceramic member are connected by using (a) glass consisting of 10.about.65 wt % of SiO.sub.2, 30 wt % or less of Na.sub.2 O, and the balance of B.sub.2 O.sub.3 and Al.sub.2 O.sub.3, (b) glass including less than 10 wt % of SiO.sub.2, and 30.about.80 wt % of B.sub.2 O.sub.3, (c) glass including substantially none of SiO.sub.2, and 30.about.80 wt % of B.sub.2 O.sub.3, or (d) glass consisting of 10.about.65 wt % of SiO.sub.2, 20 wt % or less of Na.sub.2 O, 30 wt % or less of Al.sub.2 O.sub.3, 20 wt % or less of MgO, and the balance of B.sub.2 O.sub.3.
