A high voltage battery is provided and includes a battery module that has a plurality of battery cells and covers disposed between the battery cells and a plurality of mounting members that fix the battery module to a vehicle body. The covers absorb heat energy between the battery cells and discharge the heat energy between the mounting members. In addition, a cooling block is disposed between the mounting members and has a coolant flowing therein which exchanges heat with the battery cells. Therefore, cooling performance of the battery is improved using a water cooling structure, a height of the mounting members integrating the battery modules with each other is secured to increase structure rigidity and a height of a case of the battery is minimized, thereby improving volume energy density of the battery and preventing generation of a high voltage short-circuit even though the coolant leaks during a vehicle collision.
