a gusset sheet portion connected to the front sheet portion and the back sheet portion on one side in a height direction orthogonal to the front-rear direction, wherein
each of the front sheet portion and the back sheet portion includes a first end portion located on the one side in the height direction, a second end portion located on the other side in the height direction, a first side end portion located on one side in a width direction orthogonal to the front-rear direction and the height direction, and a second side end portion located on the other side in the width direction,
the pouch container further includes:
a first joining portion connecting a peripheral portion of the gusset sheet portion to the first end portion of the front sheet portion and the first end portion of the back sheet portion in an annular shape,
a second joining portion joining the second end portion of the front sheet portion and the second end portion of the back sheet portion,
a first side-end joining portion provided connecting a one-side end portion of the first joining portion located on the one side in the width direction and a one-side end portion of the second joining portion located on the one side in the width direction, the first side-end joining portion joining the first side end portion of the front sheet portion and the first side end portion of the back sheet portion, and

a width of the gusset sheet portion in the width direction is larger than a width of the second joining portion in the width direction, and
the first side-end joining portion includes a first inclined portion extending outward in the width direction as extending from the one-side end portion of the second joining portion toward the one side in the height direction, and the second side-end joining portion includes a second inclined portion extending outward in the width direction as extending from the other-side end portion of the second joining portion toward the one side in the height direction, and
