Abstract
A manufacturing method for an electrode plate and an electrode plate are provided. The method includes deposition-layer forming to form a deposition layer in which active material particles and binder particles are deposited on a surface of a current collecting foil and heat pressing to form an electrode layer on the surface of the current collecting foil by heating and compressing a deposition-layer-formed current collecting foil having the deposition layer on the surface of the current collecting foil. The deposition layer includes a first deposition layer placed on a side of the current collecting foil and a second deposition layer constituting a surface of the deposition layer. The deposition-layer forming includes forming the deposition layer in which a content rate of the binder particles in the second deposition layer is lower than a content rate of the binder particles in the first deposition layer.
