Japanese sun observing mission; Solar‐B (Hinode) was launched on 23‐Sep‐06. The EUV Imaging Spectrometer (EIS) on board Solar‐B will be able to observe, for the first time in Solar EUV observations, spectra and monochromatic images of non‐ionization‐equilibrium plasmas in the solar transition‐region and corona at two‐wavelength bands of 170 – 210Å and 250 – 290Å, with typical time‐resolutions of 1 – 10 seconds. Time‐dependent collisonal‐radiative model has been developed to diagnose temperatures and densities of those plasmas in the outer atmospheres of the Sun. No systematic models yet exist for iron ions of L‐ and M‐shells, which are very important for coronal plasma diagnostics. Atomic data of Fe X to Fe XV are surveyed and evaluated, and most recommended data are determined. Obtaining of the experimental data of iron ions are on‐going. EUV spectra in the wavelengths of 170 – 190Å were also taken by Large Helical Device (LHD) of NIFS, injecting iron TESPEL (tracer‐encapsulated solid pellet).
