To provide a manufacturing method for an electrode plate capable of forming an active material layer on a current collecting foil without performing a step of heating and drying an undried active material layer.SOLUTION: The manufacturing method for an electrode plate 1 includes a magnetic sucking process S31, a conveying process S32, and a depositing process S33. In the conveying process S32 and the depositing process S33, while a series of carrier groups 210 of composite carrier particles 205 alternately take a rising form FV and a falling form FD, a metal cylinder 131 and an internal magnet section 133 of a magnet roll 130 are rotated so that carrier group movement speed Vh (mm/s) moving on a roll surface 130m satisfies a range VR1 of -170≤Vh≤-40 or +40≤Vh≤+170.SELECTED DRAWING: Figure 3 【課題】未乾燥活物質層を加熱乾燥させる工程を行うことなく、集電箔上に活物質層を形成できる電極板の製造方法を提供する。【解決手段】電極板１の製造方法は、磁気吸着工程Ｓ３１と搬送工程Ｓ３２と堆積工程Ｓ３３とを備える。搬送工程Ｓ３２及び堆積工程Ｓ３３において、複合キャリア粒子２０５の一連のキャリア群２１０が立ち上がり形態ＦＶと横倒し形態ＦＤとを交互に取りつつ、ロール表面１３０ｍ上を移動するキャリア群移動速度Ｖｈ（ｍｍ／ｓ）が、－１７０≦Ｖｈ≦－４０または＋４０≦Ｖｈ≦＋１７０の範囲ＶＲ１を満たすように、マグネットロール１３０の金属筒１３１及び内部マグネット部１３３をそれぞれ回転させる。【選択図】図３
