<p>PURPOSE:To prevent data distortion generated on a magnetic recording medium arranged on the surface and the like by increasing the magnetic resistance of an electrode terminal plate, as a magnetic circuit, and by determining the coercive force on the surface end part as no more than 300e. CONSTITUTION:A negative electrode terminal plate 7 is formed out of rolled aluminum, and a negative electrode lithium 6 clad thereon is formed out of amalgam (alloy) of lithium and aluminum. A plate-shaped positive electrode complex agent 4 formed out of manganese dioxide is arranged on a separator 2 on the negative electrode lithium 6, which is covered with a positive electrode terminal plate 5 which is a current collector of positive electrodes. To inhibit residual magnetism by forming the current collector of battery out of non- magnetic metallic material, the coercive force on the end part, in particular, is determined as no more than 300e, so as to eliminate magnetization on the surface of the current collector. Even when an IC card and the like that forms a magnetic stripe on the surface, is exposed to a strong magnetic field, the distortion of a magnetic data of the magnetic stripe due to the magnetization of a stored thin type battery can thus be prevented.</p> |
