PROBLEM TO BE SOLVED: To provide an organic light emitting device using a specific carborane compound and having an extremely high efficiency and high luminance light output. In an organic light emitting device having at least a pair of electrodes including an anode and a cathode, and a layer including one or a plurality of organic compounds sandwiched between the pair of electrodes, at least one of the layers including the organic compound is provided. An organic light-emitting device containing at least one carborane compound represented by the following general formula [1]. [Chemical 1] (Wherein R1 to R4 are a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted condensed polycyclic aromatic group or a substituted group; Alternatively, it represents an unsubstituted fused polycyclic heterocyclic group, which may be the same or different, and L represents an integer of 1 to 20.
