PROBLEM TO BE SOLVED: To provide a method for manufacturing a back plate for a plasma display panel capable of obtaining step-formed ribs by a simple method. SOLUTION: The method for manufacturing a back plate for a plasma display panel includes steps of: preparing a back plate forming member formed by laminating a substrate, an address electrode layer of a pattern shape and a dielectric layer in this order; forming a first rib material layer on the dielectric layer of the back plate forming member; forming a stop layer suppressing grinding by blast treatment on the first rib material layer; forming a second rib material layer on the stop layer; forming a pattern for forming the step-formed ribs having a specific function on the second rib material layer, and carrying out the blast treatment to the step-formed rib forming pattern from the vertical direction.
