In order to obtain a paper container with which it is possible to achieve safety by smoothing the corners of a seal part in a bottom part and preventing scratching on the hands of a person or on other containers during handling, and with which it is furthermore possible to improve design properties of the paper container, the present invention provides a paper container in which: first and second outside bottom-surface panels 12, 13 and first and second inside bottom-surface panels 16, 17 are folded to the inside, the panels 12, 13, 16, 17 being connected to a trunk-part front-surface panel 5, trunk-part left- and right-side-surface panels 6, 7, and a trunk-part rear-surface panel 8; and distal-end parts of the first and second outside bottom-surface panels 12, 13 and the first and second inside bottom-surface panels 16, 17 are overlapped and sealed hermetically to form a bottom part 9, wherein: the second outside bottom-surface panel 13 is formed such that the distal-end-direction length thereof is greater than that of the first and second inside bottom-surface panels 16, 17 and the first outside bottom-surface panel 12; and cutout parts 23 linked to the distal-end sides 16a, 17a of the first and second inside bottom-surface panels 16, 17 are formed at both distal-end sides 13a of the second outside bottom-surface panel 13.
