A driving advice provision apparatus generates an advice, based on diagnosis performed on multiple diagnosis items regarding the driving condition of the vehicle and based on the diagnosis results from those diagnosis items, and provides the generated advice to the driver. The multiple diagnosis items are classified into different categories according to the diagnosis methods. For the diagnosis items suitable to the comparative evaluation rather than the quantitative evaluation, a diagnosis result A for the previous evaluation section is compared with a diagnosis result B for the current evaluation section for yielding a comparative evaluation and for advice generation, thereby enabling an effective advice generation and provision in terms of diagnosis item category.
