A fuel-saving driving diagnostic device stores an external power amount which indicates an amount of power charged by an external device and an internal power amount which indicates an amount of power charged by vehicle driving. The fuel-saving driving diagnostic device calculates a driving power amount which indicates an amount of power required for vehicle driving based on the stored external power amount, stored internal power amount, and an amount of power a vehicle currently has, and makes a diagnosis of fuel-saving driving based on the calculated driving power amount and the stored external power amount. As a result, sufficient information is calculated for prompting the driver of a plug-in hybrid car to do the fuel-saving driving.
