PROBLEM TO BE SOLVED: To provide a vehicle alarm device having a plurality of acoustic output means in a cabin which is capable of correctly notifying a driver of the angle of the alarm sound in the vertical direction with respect to an object for alarm. SOLUTION: A plurality of acoustic output means (A, B) are installed in the vertical direction in a cabin, and an object detection means detects the horizontal distance to an object (10) for alarm. A control means obtains the horizontal distance, the height of the known eye point of a driver (20) and the look-down angle of the driver, and controls each output level of the plurality of acoustic output means installed in advance at the angles including the look-down angle of the driver as the virtual acoustic output angle.
