Abstract
An optical module includes: an image element; a prism mirror that reflects image light emitted from the image element at an inner reflection portion; a combiner that reflects the image light from the prism mirror toward a pupil position; and a barrel that is disposed between the prism mirror and the combiner and that positions the prism mirror. The barrel includes a first positioning surface brought into contact with the prism mirror in a second direction perpendicular to a first imaginary plane and parallel to a normal line of a second imaginary plane on which the image light emitted from an emission portion of the prism mirror is incident, and a second positioning portions brought into contact with the prism mirror in a third direction perpendicular to the first direction and intersecting the second direction.
