PROBLEM TO BE SOLVED: To provide an electrode in which reactivity on the boundary surface of an electrode active material, a conductive material and an electrolyte component is enhanced efficiently, even if the porosity of an electrode active material layer is relatively high or the electron conductivity is low on the surface of the electrode active material, and to provide a manufacturing method therefor.SOLUTION: In the electrode including an electrode active material layer containing an electrode active material, a conductive material and a binder, at least a part of the surface of the electrode active material is coated with a mixture of a micro conductive material where the average grain size of primary particles is 20 nm or more and 200 nm or less, and a high molecular weight binder where the average molecular weight is 1 million or more and 5 millions or less. The electrode active materials thus coated are bonded to each other by a mixture of an anisotropic conductive material where the average grain size of primary particles is 1 μm or more and 30 μm or less and has shape anisotropy, and a low molecular weight binder having an average molecular weight of 10-300 thousands to form the electrode active material layer. |
