PROBLEM TO BE SOLVED: To provide a slope frame structure, a slope face structure, and a slope frame unit made of cut lumber, having a good external appearance, and capable of being easily installed. SOLUTION: This slope frame structure installed on a slope face comprises rectangular side wire nets arranged face to face, an upper wire net connecting the upper ends of the side wire nets, and cut lumber. The cut lumber is packed in the space surrounded by the parallel side wire nets, the upper wire net and the slope face. Intersection plates are mounted on the slope frame structures, and the slope frame structures can be fixed to the slope face by support materials via the intersection plates so that at least the cut lumber in one direction is connected together below the intersection plates. A vegetation base material mainly made of lumber chips can be arranged in the areas surrounded by the slope frame structures.
