A vehicular data recording apparatus includes crash detection portion (12) for detecting a crash of a vehicle, and recording process portion (14) for recording and retaining output data of various vehicle-mounted sensors (20, 30, 40, 50) mounted in the vehicle, in a non-volatile memory (70). If a crash is detected by the crash detection portion (12), a data recording/retaining process relevant to the crash is performed by the recording process portion. If a plurality of crashes different in the crash form are detected continually in a short time by the crash detection portion, the recording process portion performs the data recording/retaining process relevant to each crash in accordance with a predetermined order of priority based on the crash form of each crash.
