## Claims

### Claim 1

An electric vehicle, comprising:
a pair of left and right batteries;
a pair of left and right battery-holding portions which respectively hold the left and right batteries;
a pair of left and right battery connection terminals which are provided on inner sides of the left and right battery-holding portions in a vehicle width direction and connected respectively to the left and right batteries;
an electric motor connected to a drive wheel; and
a control unit which controls charging and discharging between the electric motor and the left and right batteries,
wherein a pair of left and right battery wirings which correspond respectively to the left and right batteries are provided between the left and right battery-holding portions,
the right battery wiring is connected to the right battery connection terminal from a side inward in the vehicle width direction from the right battery-holding portion,
