The present invention is a bottle (1, 2, 3, 4) formed of a synthetic resin material in a bottomed cylindrical shape, wherein the bottle is provided with a plurality of circumferential grooves (15) that pass completely around a body (13) and extend continuously, and that are formed with gaps in the vertical direction. The circumferential grooves (15) form a wave shape extending regularly across the circumferential direction while bending in the vertical direction viewed from the side of the body (13), individual phases of the circumferential grooves (15, 15) that are adjacent in the vertical direction being displaced from each other. |
