An object of the present invention is to provide a storing tray and a storing device whereby an object such as an electronic component to be stored can be picked up in a preferred manner and a plurality of stored objects can be flipped and transferred at once. Another object is to form the storing tray as a soft tray. The storing tray includes a storing part on its main surface, the storing part including a storing base for placing therein an object such as an electronic component, a plurality of convex portions formed along the outer periphery of the storing base to protrude upward more than the storing base, and concave portions formed along the outer periphery of the storing base between the plurality of convex portions to be recessed downward more than the storing base. The storing tray has an uneven back surface opposite in shape to the main surface.
