A lighting reflection apparatus is provided, which improves controllability and sensitivity in changing or controlling an outgoing light characteristic. A reflector is composed of a substrate made of a film-like polyimide molded item shaped using only a difference between pressures applied from respective surfaces of a film-like item while subjecting the film-like item to plasticization with non-contact heating and having in itself a power of maintaining a three-dimensional shape independently or in the form of a single layer, and a reflection surface formed on an inner surface of the substrate. Then, outgoing light is changed or controlled by causing elastic deformation in the reflector by pressing the reflector with pressing means. Since the reflection surface of the reflector is formed by complete non-contact method, it is so smooth that sensitivity in controlling the outgoing light can be improved. Also, since the reflector made of an elastic film is deformed, satisfactory controllability can be attained.
