An analysis is made of a transition to a resistive state occurring under the action of the transport current in wide w>>lambda/sub perpendicular/ (w is the width and lambda/sub perpendicular/ is the effective depth of penetration of a magnetic field) superconducting films. It is shown that the presence of internal defects ensures, in contrast to the models used earlier, that vortex pairs penetrate the film. A theoretical calculation is made of the conditions for the penetration of a magnetic flux by determining the distribution of the superfluid velocity near a region of size l<
