Abstract

Provided is a manufacturing method of a compacted strip-shaped electrode plate including: an undried layer forming step of forming, on a current collector foil, a strip-shaped undried active material layer by rolling out a particle aggregate; a drying step of drying the undried active material layer to form an active material layer; and a pressing step of pressing the active material layer by rollers to compact the active material layer. The particle aggregate is a mixed particle aggregate in which first wet particles manufactured with the content ratio of conductive particles to the total solid content set to W1 and second wet particles manufactured with the content ratio of conductive particles to the total solid content set to W2, W2 being higher than W1, are mixed together.
