  The electric charge density in mesoscopic superconductors with circular
symmetry, i.e. disks and cylinders, is studied within the phenomenological
Ginzburg-Landau approach. We found that even in the Meissner state there is a
charge redistribution in the sample which makes the sample edge become
negatively charged. In the vortex state there is a competition between this
Meissner charge and the vortex charge which may change the polarity of the
charge at the sample edge with increasing magnetic field. It is shown
analytically that in spite of the charge redistribution the mesoscopic sample
as a whole remains electrically neutral.
