PURPOSE:To improve processability and productivity and to stabilize characteristics for a long term by allowing a spiral spacer to tightly and rigidly secure a solid electrolytic plate with a seal plate through heating and melting of a protruding body of a mixture of glass and heat-proof very fine particles of a predetermined particle size and a film made of glass. CONSTITUTION:A spiral spacer 5 is placed between one surface of a solid electrolytic plate 1 and a seal plate 6. The solid electrolytic plate 1 with conductivity of oxygen ions has electrode films 2 formed at either face thereof. A protruding body 5a of a mixture of glass of the spacer 5 and heat-proof very fine particles of a predetermined particle size is tightly secured, via a film 5b made of glass, between the electrolytic plate 1 and seal plate 6 through heating and melting. A scattering hole 7 is formed in the spiral room and the oxygen is scattered through this room to the electrode film 2. Therefore, the scattering hole 7 is formed with good productivity simultaneously when the electrolytic plate 1, seal plate 6 and spacer 5 are bonded. Since the scattering hole 7 is formed parallel to the electrolytic plate 1, invasion of dust or foreign substance can be prevented. Moreover, the scattering hole 7 can be formed in the periphery of the electrode film 2 with a large opening area and a large length, thus improving the accuracy in size. |
