A vacuum contact printing apparatus includes: a transparent plate on which an original film and a photosensitive material are placed, an overlay sheet which covers the transparent plate, a friction reducing sheet provided between the transparent plate and the overlay sheet, and an evacuating device for removing air from between the overlay sheet and the transparent plate. The transparent plate is covered with the friction reducing sheet prior to or simultaneously with the covering of the original film and photosensitive material placed on the transparent plate wiht the overlay sheet. Frictional force caused by the change of the form of the overlay sheet can be prevented from being applied to the photosensitive material because the overlay sheet smoothly slides on the friction reducing sheet.
