A sealing glass of a low melting point phosphate glass composition contains 15 to 35% of BaO and SbO(in total) and the ratio by weight of BaO to SbOor SbOto BaO is 0.3 or less. Particularly the transition metal is vanadium and the glass contains VOof 45 to 60 wt % as vanadium oxide and POof 15 to 30 wt % as phosphorus oxide. The bonding material is a mixture of a filler and a vanadate-phosphate glass that contains VOof 45 to 60%, POof 20 to 30%, BaO of 5 to 15%, TeOof 0 to 10%, SbOof 5 to 10%, and WOof 0 to 5%. The particle size of the filler is in the range of 1 to 150 &#x3bc;m and the ratio of filler is 80% by volume or less of the adhesive glass.
