PROBLEM TO BE SOLVED: To provide a method for manufacturing a natural stone panel, wherein a plurality of natural stones are solidified in a state arranged almost in parallel to a curved surface, capable of realizing a tunnel, a culvert, a bridge, a water channel, a breast wall or the like having semipermanent durability. SOLUTION: The method for manufacturing the natural stone panel includes a process for arranging a large number of natural stones having a large diameter on the upper surface of a lower form including a bottom plate of which the upper surface is formed into a recessed or projected curved surface, a process for spreading a particulate material such as sand or the like all over the upper surface of the bottom plate from many gaps between a large number of natural stones up to a thickness having a dimension half or less the height of the natural stones at most to arrange a large number of natural stones having a small diameter in many gaps of the large natural stones, a process for attaching an upper form having a planar shape almost same to that of the lower form to the upper part of the lower form, a process for putting a solidifying material such as ready-mixed concrete or the like in the lower form so that the upper surface thereof becomes a curved surface almost parallel to the upper surface of the bottom plate of the lower form and a process for washing off the particulate material after curing and demolding.
