PROBLEM TO BE SOLVED: To obtain an adhesive-conveyor-tool-applicable metal mask reducing adhesion of a part protruding from a substrate outline on a side of a substrate contact surface of the metal mask to an adhesive part of an adhesive conveyor tool in cream-solder-printing a substrate, enabling a plate to smoothly separate and shortening tact time. SOLUTION: The adhesive-conveyor-tool-applicable metal mask 3 to be used in cream-solder-printing the substrate has a frame-like recess 31 formed to avoid contact with the adhesive part of the adhesive conveyor tool in squeezing within an adhesive part contact region of the tool on the side of the substrate contact surface of the metal mask and except the substrate contact part. The size of the outer periphery of the frame-like recess is structured to be smaller than an outer peripheral region of the adhesive part of the adhesive conveyor tool. Numerous micro recesses 34 for reducing a contact area are formed along a flat inner periphery of the periphery of the metal mask in contact with the outer peripheral region of the adhesive part of the tool at squeezing.
