A foamed and stretched plastic bottle having, in the body portion thereof, a foamed region in which foamed cells are distributed, wherein, in at least a portion of the foamed region, the lengths of the foamed cells in the axial direction of the bottle are so distributed as to gradually decrease as the positions of the foamed cells shift from the outer surface side of the body portion toward the central portion thereof and then gradually increase as their positions shift from the central portion thereof toward the inner surface side thereof. The foamed and stretched plastic bottle of the invention exhibits excellent light-shielding property.
