Abstract

PURPOSE:To eliminate the unbalance of the tension of a bag, and to prevent the generation of the dislocation of the upper and lower substrates, by holding a cell in a position where the interval of the inner peripheral edge of an annular plate material having the thickness of 1.5-3 times of the thickness of the cell and having a groove part on a surface, and the outer peripheral edge of the smaller substrate of the cell becomes symmetrical against the center of the smaller substrate. CONSTITUTION:Large and small substrates 1, 2 with an electrode are opposed through a thermosetting sealing material 13 and a spacer material 14 and aligned exactly, thereafter, stuck to each other, and formed so that the center of the smaller substrate 2 becomes eccentric relatively in the left direction of the paper surface against the center of the larger substrate. The stuck cell 3 is inserted into a bag-like heat resisting film 16, in a state that it has been held in a planar jig. It is brought to pressure reduction by using a vacuum packing machine, thereafter, the film 16 is sealed by a heat seal 17, and the periphery is returned to the atmospheric pressure. Accordingly, the cell 3 is pressurized by the atmospheric pressure through the film 16. In such a way, since the cell 3 is positioned so as to become symmetrical against the center of the substrate 2, the tension of a bag becomes equal at both sides, and the dislocation of the upper and lower substrates is not generated.
