Abstract
A producing method for a positive electrode plate includes a second coating process of coating a second positive electrode paste on either a surface of a first positive electrode paste layer which is formed on a current collector or a surface of a positive electrode mixture layer that has been formed by drying the first positive electrode paste layer, a drying process of drying the first positive electrode paste layer with the second positive electrode paste layer or a drying process having a first step of drying the first positive electrode paste layer to form the first positive electrode mixture layer and a second step of drying the second positive electrode paste layer coated on the surface of the first positive electrode mixture layer to form the positive electrode mixture layer. An average length of first carbon nanotubes is longer than an average length of second carbon nanotubes.
