The purpose of the present invention is to obtain an easily flatly foldable paper container having a top part in which a top surface is an inclined surface. In a paper container having an inclined surface at a top part thereof, body-part left and right lateral surface panels have first folding inclined folding lines 40 and 41 that form triangles C point-symmetrical with triangles A formed in lateral surface panels 17 and 18 using middle points M of second top part lateral folding lines 15 and 16 as symmetrical centers, and second folding inclined folding lines 42 and 43 that form triangles D line-symmetrical with triangles B formed in inner bottom surface panels 26 and 27 using second bottom part horizontal folding lines 24 and 25 as symmetrical axes. A body part panel has body part vertical folding lines 44 and 45 that connect apexes P3 of the triangles C and apexes P4 of the triangles D to each other, a first folding horizontal folding line 46 that connects the apexes P3 of the triangles C to each other, and a second folding horizontal folding line 47 that connects the apexes P4 of the triangles D to each other.
