摘要： Provided are: a rare earth complex which has a novel structure, which exhibits compatibility with organic solvents and resins, and which exhibits excellent luminescent properties as a luminescent element; and a use thereof. This rare earth complex includes: a phosphine oxide compound represented by general formula (1); at least one rare earth ion selected from the group consisting of Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu; and a ligand compound. In the rare earth complex, the coordination numbers of the ligand compound and the phosphine oxide compound represented by general formula (1) to the rare earth ion are 8-10, and a plurality of the phosphine oxide compounds represented by general formula (1) and a plurality of the rare earth ions are provided with a crosslinked structure.
