To suppress generation of foreign matters due to abrasion, impact or the like during handling such as transportation and storage and generation of foreign matters by friction of a polypropylene band, to prevent a peripheral portion of an etched component from bending, and to reduce failures of the component by using a presser plate for packing the etched component.

Two plastic corrugated board sheets are stuck, and rib directions of the two sheets 54a and 54b are orthogonal to each other. The component is tied with a band and packed with a lower presser plate and an upper presser plate disposed so that a rib direction of an upper layer 61a of the lower presser plate is in parallel to a rib direction of an upper layer 62a of the upper presser plate.
