Abstract
A projection-type image display apparatus includes a first reflecting optical element and a second reflecting optical element that are retained on a base. A base-side first positioning unit and a base-side second positioning unit are formed integrally with the base. The base-side first positioning unit abuts against the first reflecting optical element to define a position of the first reflecting optical element. The base-side second positioning unit abuts against the second reflecting optical element to define a position of the second reflecting optical element.
