1. A vehicle battery case comprising:
a case body in which a vehicle battery is contained; and
a side portion extending in a longitudinal direction of a vehicle and coupled to a side of the case body, thereby protecting a side of the vehicle battery,
wherein the side portion comprises:
a lower panel extending outwards from the case body and having a first protrusion formed to protrude upwards;
an upper panel disposed above the lower panel and extending outwards from the case body so as to form a closed section together with the lower panel;
a reinforcement panel disposed between the upper panel and the lower panel so as to extend outwards from the case body, thereby reinforcing rigidity of the side portion together with the lower panel and the upper panel; and
multiple pipe members penetrating the lower panel, the upper panel, and the reinforcement panel and connecting with a chassis, while being disposed to be spaced apart in forward or backward direction of the vehicle.
