Provided is a container having a panel structure that can secure load resistance and heat resistance even in a reduced weight of the container and can suppress reduced-pressure deformation after filling. The shoulder part 3 has a panel surface part 12 expanding in a truncated cone shape from the mouth part 2 toward the trunk part 4, an arc-shaped edge reinforcing rib part 14 formed on a panel surface outer edge 13 forming a boundary between the shoulder part 3 and the trunk part 4 intermittently along the axis of the container 1, The edge reinforcing rib part 14 forms a recess 16 recessed to the radial inside of the container 1, the support rib part 15 forms a protrusion 19 swelling to the radial outside of the container 1 from the recess 16 of the edge reinforcing rib part 14, and has a panel structure in which the recess...
