To provide a power battery pack that has advantages, such as a high space utilization factor, a large energy density, and a high cruising capability, and to provide an electric automobile, and a single battery included in the power battery pack.SOLUTION: Provided is a single battery in which a battery main body included in the single battery has a length L, a width H, and a thickness D, the length L being larger than the width H, the width H being larger than the thickness D. The battery main body satisfies relations of 400 mm≤L≤2,500 mm and L/V=0.0005 mm-2 to 0.002 mm-2. A power battery pack includes a pack main body, and a plurality of single batteries therein. Each single battery has a length L0, a width H0, and a thickness D0 that satisfy L0>H0≥D0. In a case where the power battery pack is arranged on an electric automobile, the single battery extends so that its longitudinal direction is along a width direction or a longitudinal direction of the electric automobile. In a case where the single battery extends so that its longitudinal direction is along the width direction of the electric automobile, the length L0 of the single battery and a dimension W in the width direction of a vehicle body of the electric automobile satisfy 46%≤L0/W≤76%.SELECTED DRAWING: Figure 2
