A beverage container according to the present invention includes a bottom wall portion, and a side wall portion extending upward from a circumferential edge of the bottom wall portion, and due to an outer diameter of the bottom wall portion being formed smaller than an outer diameter of the side wall portion, a annular stepped portion is formed at a lower end of the side wall portion, a plurality of recessed portions and a plurality of protruding portions that are alternately arranged in a circumferential direction are formed on the stepped portion, and a width of the stepped portion is larger than a width of an upper end of the side wall portion at at least portions where the recessed portions are formed.

1 . A beverage container comprising:
 a bottom wall portion, and   a side wall portion extending upward from a circumferential edge of the bottom wall portion,   wherein, due to an outer diameter of the bottom wall portion being formed smaller than an outer diameter of the side wall portion, an annular stepped portion is formed at a lower end of the side wall portion,   the step portion is provided with a plurality of recessed portions and a plurality of protruding portions that are alternately arranged in a circumferential direction, and   a width of the stepped portion is larger than a width of an upper end of the side wall portion at at least portions where the recessed portions are formed.   
     
     
         2 . The beverage container according to  claim 1 ,
 wherein the width of the stepped portion is substantially the same as the width of the upper end of the side wall portion at portions where the protruding portions are formed.   
     
     
         3 . The beverage container according to  claim 1 ,
 wherein a depression is formed in a lower surface of the bottom wall portion, and   grooves that bring an outer circumferential surface of the bottom wall portion into communication with the depression are respectively formed at portions where the recessed portions are formed.   
     
     
         4 . The beverage container according to  claim 1 , further comprising
 an annular elevation that downwardly extends from the lower surface of the bottom wall portion and has an outer diameter that is smaller than the outer diameter of the bottom wall portion.   
     
     
         5 . The beverage container according to  claim 3 , further comprising
 an annular elevation that downwardly extends from the lower surface of the bottom wall portion and has the outer diameter that is smaller than the diameter of the bottom wall portion,   wherein gaps that are continuous with the grooves are formed at respective portions corresponding to the grooves.   
     
     
         6 . The beverage container according to  claim 1 ,
 wherein the recessed portions and the protruding portions are formed into a continuous wave shape in a side view.
