  "textContent": "There is provided a nonaqueous electrolyte secondary battery in which lithium ions can move smoothly between a positive electrode and a solid electrolyte layer, the nonaqueous electrolyte secondary battery having improved internal resistance. [0002] The nonaqueous electrolyte secondary battery includes a positive electrode 1, a negative electrode 2, and a solid electrolyte layer 3 arranged between the positive and negative electrodes. The positive electrode 1 includes a positive-electrode sintered body 10 formed by firing a powder containing a positive-electrode active material and includes a cover layer 11 arranged on a surface of the positive-electrode sintered body 10 adjacent to the solid electrolyte layer 3, the cover layer containing a positive-electrode active material. The cover layer 11 contains a compound having a layered rock-salt structure. Preferably, the direction of the c-axis of the crystal of the compound is not perpendicular to the surface of the positive-electrode sintered body. More preferably, a buffer layer 4 composed of LiNbOis arranged between the positive electrode 1 and the solid electrolyte layer 3, the buffer layer being configured to reduce interface resistance.",
