<P>PROBLEM TO BE SOLVED: To provide a partition member that can be efficiently assembled and disassembled and excels in cushioning capability. Ž<P>SOLUTION: A partition member 20 is made of corrugated cardboard 1 with an intermediate core 4 between a pair of sheets 2 and 3. In the partition member 20, a blank sheet includes: a pair of wall sectioning valley fold lines 24, 24 extending parallel; three or more partitioning mountain fold lines 25 extending perpendicular to the wall sectioning valley fold lines 24; partitioning valley fold lines 26 extending parallel to the partitioning mountain fold lines 25; a plurality of bottom portions 21 that have side raising mountain fold lines 27 extending outward in the directions of the corresponding partitioning mountain fold lines 25 from the corresponding intersections of the valley fold lines 24 and 26 and that are folded to have a wave form in an assembled state; a plurality of overlapping parts 22 made to overlap the surfaces of the bottom portions 21; and a plurality of side portions 23 extended upwards from the bottom portions 21. Each partitioning mountain fold line 25 except part of the side portion 23 is formed from a half-cut line 25b formed by cutting the first sheet 2 of the corrugated cardboard 1 situated at the top in a mountain-folded state and by not cutting its second sheet 3 situated opposite.
