PROBLEM TO BE SOLVED: To provide an excellent electrode sheet.SOLUTION: A laminated electrode body is formed by laminating a negative electrode sheet having a first electrolyte layer laminated on both sides of the negative electrode sheet, and a second electrolyte layer on at least one side of the first electrolyte layer, and a positive electrode sheet having a second electrolyte layer laminated on at least one side of the positive electrode sheet, while facing the second electrolyte layers each other. The first electrolyte layer has an electrolyte density higher than that of the second electrolyte layer. 【課題】良好な電極シートを提供すること。【解決手段】負電極シートの両面上に積層した第１電解質層と、前記第１電解質層の少なくとも一方の側上の第２電解質層とを有する、負電極シートと、正電極シートの少なくとも一方の側上に第２電解質層を積層した正電極シートとを、それぞれの前記第２電解質層を対向させて積層した積層電極体であって、前記第１の電解質層が前記第２の電解質層より大きい電解質密度を有する、積層電極体。【選択図】図２
