After HINODE started its observations in 2006, the Spectro-Polarimeter (SP) aboard Hinode has provided unique data for studies of photospheric magnetic fields. Advantages of the HINODE SP is that we can get full polarimetric and spectroscopic information on Zeeman-sensitive photospheric lines as well as stable image quality whose angular resolution is 0.3 arcsec. It allows us to carry out detailed studies on magentic and flow structures of sunspot fine structures (e.g. umbral dots, light bridges, and penumbral filaments) and properties of the quiet Sun magnetic fields, which has provided insights on how magnetic flux interacts with convective flows in the photosphere. Vector field maps generated through a Stokes inversion technique are accurate enough to track development of magnetic shear toward the onset of a flare, and are also useful to carry out the nonlinear force-free field (NLFFF) extrapolation. The weakness of the HINODE SP observations is a limited field-of-view and temporal coverage because of the scanning instrument. This is why complementary observations with SDO/HMI and SOLIS are important in the current increasing solar activity.
