Abstract
Studies on sunspots have a very long history mostly supported by ground-based observations. However, the detailed evolution of sunspot magnetic field structures are revealed by Hinode observations of accurate photospheric magnetic fields at high spatial resolution under the seeing-free conditions. After the launch of Hinode, the radiative three-dimensional magnetohydrodynamic simulations successfully demonstrated sunspots. The combination of good observations and simulations results in rapid advancement in our knowledge about sunspots. Especially, fine-scale structures in sunspots are commonly understood as a manifestation of the magneto-convection .
