To provide a corner member which eliminates a clearance in a direction orthogonal to a stacking direction and can be easily destacked.

The corner member 1 includes: a columnar portion 10 extending in a direction of stacking a panel-like product P to receive the weight of the product; and a receiving portion 40 on which a corner of the panel-like product P is placed. The columnar portion 10 has a circumferential wall forming a substantially orthogonal corner, and the receiving portion 40 has a terrace-like bottom surface 41 horizontally protruding inward from the lower side of the circumferential wall. Inclined surfaces 12x, 12y of the inner surface of the circumferential wall abut on inclined surfaces 47x, 47y of the outer surface of the bottom wall surface 41 to prevent slip in positive or negative X- or Y-direction. Further, inclined surfaces 23x, 23y of the upper surface of the circumferential wall surface abut on inclined surface of the lower surface of the circumferential wall surface to prevent slip in negative or positive X- or Y-direction.
