Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a shadow mask which cuts the shadow mask in a wafer-like shape without using a cutting machine constituted of a stationary blade and a moving blade when the shadow mask of which the many sides are attached to a lengthy belt-shaped metal sheet is cut into the wafer-like shape.
SOLUTION: The metal sheet is cut by irradiating a laser beam while moving a laser beam source 30 installed above the metal sheet 1 in the width direction Y of the metal sheet. The metal sheet is cut in the lengthy belt-shaped direction of the metal sheet while the transfer of the laser beam source is made in the lengthy belt-shaped direction X of the metal sheet. The laser beam source should be YAG or CO
2 laser.

Abstract: PROBLEM TO BE SOLVED: To provide highly moisture-proof outer packaging antirust paper for a shadow mask wherein there is no paper dust or discoloration of a shadow mask occurring when the shadow mask is packed, and no rust is allowed to occur on the shadow mask even if the mask is stored under a highly moist environment for a long time. SOLUTION: The outer packaging antirust paper to be used for packing a shadow mask comprises a three-layered structure comprising a synthetic resin sheet having a plurality of fine pores and neutral paper laminated on both surfaces of the resin sheet. The neutral paper on a surface in contact with the shadow mask contains an antirust agent.
