The spin-resolved circularly polarized photoemission measurement of Ca2RuO2 was carried out. It was found that the strong spin-orbit coupling induces the substantial orbital angular momentum in the Ru 4d t2g band. The large temperature dependence of the 0 1s XAS data shows that the orbital population of the t2g band is drastically changed by the small compression of the RuO6 octahedra and the strong spin-orbit interaction.
