PROBLEM TO BE SOLVED: To provide a plate material machining surface plate which can improve the flatness of a plate material surface, eliminate a level difference in a scanning line, and cope with various kinds of material qualities. SOLUTION: This plate material machining surface plate includes: a flexible variable plate body 2 supporting a plate-like workpiece W on one face; and a copying support means 3 supporting the other face of the variable plate body 2 and deforming the variable plate body 2 to be rugged according to the back rugged part of the plate-like workpiece W, wherein when a machining tool is pressed to the surface of the plate-like workpiece to perform flattening, the copying support means 3 is moved forward and backward according to the back rugged part of the plate-like workpiece W to prevent the back rugged part of the plate-like workpiece W from being transferred to the surface of the machined plate-like workpiece W.
