Evolution of the magnetic field of a neutron star (pulsar) under the influence of the superconductivity of a proton plasma in the stellar core is considered. The magnetic field expulsion from the core due to the Meissner effect for the second-type npe-superconductor is shown to be inefficient for the magnetic fields B 0<1014 G. Therefore, neglecting other expulsion mechanisms (e.g., related to the buoyancy of the Abrikosov vortices or their pinning to the Onsager-Feynman vortices in the superfluid interior of the rotating star), such magnetic fields should be frozen into the core for>1010 years, i.e., during the entire lifetime of the star.
