A structure for mounting electronic apparatuses in an electric motor-driven vehicle has a pair of first brackets each having a base part that is fixed to the side face of a chassis frame extending in the longitudinal direction of the vehicle and an arm part extending in the lateral direction of the vehicle. A pair of second brackets is fixed to the upper surfaces of the arm parts such that they extend in the longitudinal direction of the vehicle with a space between them. A battery unit is placed on the upper surfaces of the second brackets, and an electronic apparatus unit is placed under the battery unit between the second brackets. The structure enables electronic apparatuses to be mounted compactly, improves the efficiency of the electric motor by reducing the length of high voltage electric cables, and increases the available space for mounting the refrigerating system.
