    Abstract: PROBLEM TO BE SOLVED: To reduce a gaseous product by disposing a seal made of a glass rod and a spacer having a higher melting point and a greater height at the outer periphery of a screen between upper and lower plates respectively having an anode and a cathode, followed by heating up to a predetermined temperature in a vacuum. SOLUTION: A seal 20 formed of a soluble glass rod is stuck to the outside circumference of an acting area of a screen on a plate 4 with an anode formed thereon. A few glass spacers 22 are temporarily interposed between the seal 20 and the outside circumference of the acting area of the screen. A melting point of the glass of the spacer 22 is higher than that of the glass forming the seal 20, and considerably higher at that. A plate 1 with a cathode/grid formed thereon is placed on the plate 4, is heated in a vacuum at temperatures higher than the melting point of the seal 20 but lower than the melting point of the spacer 22, followed by mechanical pressing. Consequently, the spacer 22 is crushed, so as to be sealed therearound in a predetermined height by melting of the seal 20.
