The image display apparatus includes an optical system causing a light flux entering from an original image through an entrance surface to reflect at a part of reflective surfaces, causing the reflected light flux to form an intermediate image, and then causing the light flux to reflect at another part of the reflective surfaces and exit from an exit surface toward an exit pupil located in a first direction. The optical element includes a first optical portion, a second optical portion provided in a second direction orthogonal to the first direction with respect to the first optical portion, and a connection portion to be connected to a holding portion provided in the apparatus. The connection portion is formed on a side face of the first optical portion so as to be included within a maximum width of the second optical portion.
