An electric bus (1, 400), comprising: an electricity storage function unit; a power receiving unit that is adapted to receive electric power supplied from an external charging device by coming into contact with a power supplying unit of the external charging device; a charger that is adapted to charge the electricity storage function unit with the electric power received from the power receiving unit; a driving unit that is adapted to drive the electric bus (1, 400) by receiving supply of the electric power from the electricity storage function unit; one or more doors (2, 3) installed at an entrance and exit portion; a first controller that is adapted to transmit a first signal to the external charging device upon detecting at least one of the doors (2, 3) is opened, the first signal including information capable of identifying an attribute of the electric bus (1, 400) and instructing the external charging device to start charging the electricity storage function unit, and that is adapted to transmit a second signal to the external charging device upon detecting all the doors (2, 3) are closed, the second signal instructing the external charging device to stop charging the electricity storage function unit; characterized by the electric bus (1, 400) further comprising: a switching unit that is adapted to switch modes between a first mode and a second mode, the first mode being a mode in which charging the electricity storage function unit starts or stops according to a detection result of whether the door (2, 3) is opened or closed, the second mode being a mode in which charging the electricity storage function unit starts or stops according to an operation on a first button, wherein the first controller is adapted to transmit the first signal or the second signal to the external charging device according to the detection result of whether the door (2, 3) is opened or closed when the mode is switched to the first mode, and is adapted to transmit the first signal or the second signal to the external charging device according to an operation on the first button when the mode is switched to the second mode. an electricity storage function unit;
