Abstract

An electrode body comprising a positive electrode mixture layer, a negative electrode mixture layer, and a thermoplastic-resin separator layer interposed therebetween is manufactured. A manufacturing method of the electrode body includes a preprocessing step of preprocessing a portion to be cut in a long-strip shaped integrated structure in which the separator layer as an accumulated layer of resin particles are interposed at least between the positive and negative electrode mixture layers such that the positive electrode mixture layer, the negative electrode mixture layer, and the separator layer are lowered their volume porosities to 10 to 20%, 10 to 20%, and 5% or less, respectively, and a cutting step of cutting the portion of the long-strip shaped integrated structure having been lowered the volume porosity by a cutting blade.
