A head-up display apparatus having a structure capable of imaging a user, and enabling an eye position of the user to be accurately calculated is provided. The head-up display apparatus reflects visible light L emitted from display means 2 toward the user D by a combiner member (concave mirror) 4 to form a display image V. The apparatus includes infrared ray emitting means 5 for emitting an infrared ray toward the user D, a mirror member (cold mirror) 3 for reflecting the visible light L emitted from the display means 2 toward the combiner member 4, and transmitting the infrared ray reflected by the user D and the combiner member 4, a plurality of imaging means 6, 7 disposed to face the mirror member 3 for sensing the infrared ray, and each imaging the user D from differing directions, and image processing means 8 for calculating the eye position of the user D based on an image captured by the imaging means 6, 7.
