A tray is provided to secure safety in transferring a plurality of stacked trays by firmly coupling the trays through a plurality of stacking protrusions formed on frames of the trays. A tray(100) includes a main body(110) and a frame(120). The main body has a containing space(121) to contain a flat type object therein. The frame is formed at an upper end of the tray body to be extended outward. The main body has a plurality of support blocks(130a-130c) to support the flat type object to the containing space of the main body. Each of the support blocks has a plurality of support protrusions arranged at regular intervals to elastically support the flat type object. The frame has a plurality of stacking protrusions(122) on an upper surface. Inner surfaces of the stacking protrusions are in contact with an outer surface of the main body when a plurality of trays are stacked.
