In order to explore the metallicity of high-z dusty galaxies in the evolving phase, mid- and far-infrared line diagnostics by using deep spectroscopy with SPICA are extremely powerful. We here propose to use far-infrared [O III] and [N III] lines to study the metallicity in dustenshrouded parts in galaxies.
Key words: Galaxies: evolution / Infrared: spectroscopy / Missions: SPICA
