[0029] The drawing shows an example of a primary battery of a flat battery which is the object of the present invention. As shown in FIG. 1, the battery container 1 is composed of a shallow dish-shaped positive electrode case (exterior case) 3 opening upward and a shallow dish-shaped negative electrode case (sealing cover) 5 opening downward, and the whole is formed into a flat coin shape. The nominal voltage of the flat battery described above is 3V. Inside the battery container 1, the power generation element 2 is housed, and an annular gasket 6 is arranged between the positive electrode case 3 and the negative electrode case 5.
[0030] In addition, with the power generating element 2 contained in the positive electrode case 3, the negative electrode case 5 is inserted into the inner edge of the opening of the positive electrode case 3 via the gasket 6 and fixed by riveting (the state of FIG. 1), forming a sealing gasket. 6 The battery container 1 is sealed between the positive...
