A switch (82) sets the voltage level of a control line (81) to a first level corresponding to a first voltage by electrically coupling the control line (81) with a first node (85) when manual operation is not executed. The switch (82) sets the voltage level of the control line (81) at a second level corresponding to a second voltage by electrically coupling the control line (81) with a second node during a period of time over which manual operation is executed. An ECU (30) switches the operation mode of a hybrid vehicle (1000) having first and second power sources between a first mode in which the first power source is used having higher priority for the running of the hybrid vehicle (1000), and a second mode in which said second power source is used having higher priority for the running of the hybrid vehicle (1000), based on a change of the voltage level of the control line (81) from the first level to the second level, and the change of the voltage level of the control line (81) from the second level to the first level.
