The effects of an electric field on quantum well QW potential profile and position of bound states there are investigated. It is shown that the electric field applied on a symmetrical quantum well transforms it into asymmetrical one and at strong electrical field into triangular one and the energy of a bound state decreases with an increase of field as long as the level of energy remains in quadrangular well region. In strong electrical fields the energy level are shifted into triangular well region. that determines the increasing of bound state energy concerning the well middle with field increasing.
