We studied 16 sunspots with different sizes and shapes using the observationswith the Hinode Solar Optical Telescope. The ratio of G-band and CaII H imagesreveal rich structures both within the umbra and penumbra of most spots. Thestriking features are the compact blob at the foot point of the umbra side ofthe penumbral fibrils with disk center-limb side asymmetry. In this paper, wepresent properties of these features using the spectropolarimetry and images inG-band, CaII and blue filters. We discuss the results using the contemporarymodels of the sunspots.
