PROBLEM TO BE SOLVED: To provide a device capable of easily improving a skill of ecological driving.SOLUTION: When a start/end button is depressed to become an ON state, the ecological driving learning device starts to collect measurement values of vehicle states such as a fuel injection amount and an engine speed (S220), and measures a degree of the ecological driving such as fuel consumption (S225 and S230). When the start/end button is depressed again to become an OFF state, the ecological driving learning device displays a degree of the ecological driving in the entire measurement period when the button is in the ON state and degrees of the ecological driving measured in the previous time and the last time but one (S260). When an interruption/restart button is depressed in the measurement period (S210: Yes), the ecological driving learning device temporarily interrupts the collection of the measurement values of the vehicle states in the interruption period till the button is depressed again, and measures the degree of the ecological driving of the entire measurement execution period obtained by subtracting the interruption period from the measurement period.
