A package (1) of the present invention includes: stacks (5) each including a plurality of brittle thin-sheet materials (50); stack holders (6) holding the stacks (5); and a packaging container including at least a body portion (4) having a plurality of recessed portions (41). The stacks (5), together with the stack holders (6), are fitted in the recessed portions (41) in such a manner that a face of each stack (5) that is formed along a stacking direction of the stack (5) faces a bottom face of the recessed portion (41). With this configuration, breakage of the brittle thin-sheet materials (50) can be reduced.
