Various theoretical and observational results have been reported regardingthe presence/absence of net electric currents in the sunspots. The limitedspatial resolution of the earlier observations perhaps obscured theconclusions. We have analyzed 12 sunspots observed from Hinode (SOT/SP) toclarify the issue. The azimuthal and radial components of magnetic fields andcurrents have been derived. The azimuthal component of the magnetic field ofsunspots is found to vary in sign with azimuth. The radial component of thefield also varies in magnitude with azimuth. While the latter pattern is aconfirmation of the interlocking combed structure of penumbral filaments, theformer pattern shows that the penumbra is made up of a "curly interlockingcombed" magnetic field. The azimuthally averaged azimuthal component is seen todecline much faster than 1/$\varpi$ in the penumbra, after an initial increasein the umbra, for all the spots studied. This confirms the confinement ofmagnetic fields and absence of a net current for sunspots as postulated by\cite{parker96}. The existence of a global twist for a sunspot even in theabsence of a net current is consistent with a fibril-bundle structure of thesunspot magnetic fields.
