Abstract
A separate supporting body for supporting semiconductor wafers of φ450 mm is attached to the inner surface of either side wall of a container body. Each supporting body is formed of a front supporting piece that is projected laterally from a frame and horizontally retains the wafer on, at least, the side part in the front peripheral edge; and a rear supporting piece that is projected laterally from frame and horizontally retains the wafer on, at least, the side part in the rear peripheral edge. Front supporting piece is formed of a projected part that extends from the front of frame toward the front peripheral edge of the semiconductor wafer and a curved part that extends rearwards from projected part along the peripheral edge of the semiconductor wafer.
