A manufacturing method in which ultrasonic vibration is applied to the lead attachment part of a unit plate of an electrode plate impregnated with an active material to expose the core metal, and a porous metal core material as described in Japanese Patent Publication No. 60-40145. There is a manufacturing method in which an electrode plate coated with a paste-like active material is removed using a rotatable disc-shaped cutting blade, and then brushed to form an exposed portion of the core material. However, all of the above conventional methods can be applied when the conductive core is a porous metal core, and when a sintered body of metal fiber is used as the core, the above conventional methods can be applied when the conductive core is a porous core. It is removed together with the fibrous body. This is because the strength of the sintered fiber body is extremely lower than that of the porous core metal, and also because the sintered fibers are dispersed.

。Another method, as described in Japanese Patent Publication No. 55-31989, is to attach a piece of adhesive tape to one or both sides of a metal core, apply a paste-like active material or active material retention agent, and dry it. Later, there is a manufacturing method in which the adhesive tape is peeled off to remove the active material or the active material holding agent. However, this manufacturing method has the disadvantage of poor productivity and is not suitable for mass production.

A strip of 0 m long is heated to a reducing temperature of 950 to 1150.
Sintering is carried out for 5-60 minutes at °C. The thickness is adjusted to 0.8 to 1.0 by roll pressing, and a slurry-like active material prepared by mixing and stirring cadmium oxide powder and metal cadmium powder with ethylene glycol is filled. The amount of filling is made uniform by scraping off excess slurry with an adjustment knife. Next, it passes through a high-pressure water spraying device equipped with a nozzle that sprays high-pressure water onto the portion where the exposed core portion shown in FIG. 1 is formed. A portion of the slurry is then washed and removed by the high pressure water stream. Thereafter, the ethylene glycol is evaporated using an infrared heater and the electrode plate is dried.
