The invention relates to a composite leather fabric with good heat insulation effect. The composite leather fabric successively comprises an inner leather layer (1), a first air-permeable layer (2), a supporting layer (3), a second air-permeable layer (4) and an outer leather layer (5), wherein the back surface of the inner leather layer is provided with a lining fabric layer which is a heat-insulation braided fabric, the heat-insulation braided fabric is mainly prepared from a proper amount of reflective yarns through braiding, and the surfaces of the reflective yarns are parallely provided with most irregular reflective surfaces. The composite leather fabric can guarantee cleanness of inner and outer surfaces and has good heat insulation effect.
