• The absorption spectra of EuAlO_3 were measured in the frequency range, 17100-21500cm^<-1>, in which the transitions from the ground state ^5D_J(J=0,1,2) states were observed. The spectral lines were assigned to the transitions to the crystalline-field split components of ^5D_J(J=0,1,2) of Eu^<3+> ions with the C_s site symmetry. The crystalline field analysis of these lines was made by assuming the approximate site symmetry C_<2v>. The observed linewidths are 3-5 cm^<-1> at 1.9°K and much broader than those in dilute YAlO_3:Eu^<3+>. Furthermore, some of the lines seem to have two components with comparable intensity. The sources of these additional broadenings and structures of the lines are discussed. Many sharp and weak satellites were observed near the main lines. The origins of these satellites are also discussed.
