<p>A tray having high impact resistance and high vibration resistance and capable of stably holding a specific number of articles. A tray (1) for containing substantially plate-shaped articles has ridges (10) and bottom surfaces (20) with each of the ridges (10) and each of the bottom surfaces (20) being alternately arranged. The ridges (10) have placement surfaces (12) which are tilted at a predetermined angle relative to the bottom surfaces (20) and on which the articles are placed. Ridges (22) are provided at the bottom surfaces (20) so as to be asymmetrical in the left-right direction with respect to a perpendicular line bisecting the length of each ridge (10) in the longitudinal direction thereof.</p>
