Abstract: To prevent occurrence of cracks without employing such a method as the precision control of sealing frit or the increase of capillary thickness. As a means for solution, about 20 times as much magnesium oxide as for a barrel portion (2) having an arcing space was added to form a capillary (3), followed by calcination at 1,200 DEG C. And after it had been connected to the separately formed barrel portion (2), the assembly was calcined again at 1,200 DEG C, and fired in a hydrogen atmosphere at 1,850 DEG C for 3 hours, with the result that whereas the mean alumina particle size for the barrel portion (2) was 32 mu m, the mean particle size for the capillary (3) was 19 mu m, giving an increase in strength.
