To provide an electrode having excellent electrode performance.SOLUTION: An electrode 10 includes: a collector 5; and an active substance mixture layer 11 that includes first particles 3, second particles 6, first active material particles 1, and second active material particles 4, which is positioned over the collector 5. The active substance mixture layer 11 includes: a first mixture layer 12 positioned over the collector 5 including the first particles 3 and the first active material particles 1; and a second mixture layer 13 positioned over the first mixture layer 12 including the second particles 6 and the second active material particles 4. In the cross-sectional view of the electrode 10, the active substance mixture layer 11 has, in at least a part, a boundary 11A where the first active material particle 1 and the second active material particle 4 are in discontinuous contact.SELECTED DRAWING: Figure 1 【課題】優れた電極性能を有する電極を提供する。【解決手段】電極１０は、集電体５と、集電体５上に位置し、第１粒子３、第２粒子６、第１活物質粒子１及び第２活物質粒子４を含む活物質合剤層１１と、を備える。活物質合剤層１１は、集電体５上に位置し、第１粒子３及び第１活物質粒子１を含む第１合剤層１２と、第１合剤層１２上に位置し、第２粒子６及び第２活物質粒子４を含む第２合剤層１３とを有する。電極１０の断面視において、活物質合剤層１１は、少なくとも一部に第１活物質粒子１と第２活物質粒子４とが不連続な状態で接している境界１１Ａを有する。【選択図】図１
