A cup part can include a bottom surface and a side surface, and a flat part disposed to surround the cup part. The side surface can include a first curved portion, a planar portion, and a second curved portion, the pouch film laminate can include a base material layer, a sealant layer and gas barrier layer disposed therebetween. The pouch-type battery case is configured to satisfy Equation 1: 0.01≤ D/{A−(R+R+C)}, where D is the gas barrier layer thickness, A is a vertical depth of the cup part, Ris a curvature radius of the first curved portion between the bottom surface and the flat part, Ris a curvature radius of the second curved portion between the planar portion and the flat part, and C is a horizontal length of the planar portion.",
