The invention provides a discharge lamp lighting device allowing a cumulative operation time of a high-frequency lighting device to be obtained and capable of correcting illuminance; and to provide a luminaire. This discharge lamp lighting device is provided with: the high-frequency lighting device for energizing a discharge lamp; a timer means for cumulatively counting the operation time of the high-frequency lighting device; a nonvolatile storage means for storing the cumulative operation time of the high-frequency lighting device cumulatively counted by the timer means; a dimming signal generation means for generating a dimming signal based on the cumulative operation time and the cumulative operation time in the latest lamp replacement; and a control means for controlling the high-frequency lighting device according to the dimming signal.
