PROBLEM TO BE SOLVED: To provide a nonionic substituted ethynyl gold-nitrogen-containing heterocyclic carbene complex exhibiting light emission in a blue region of the wavelength of 460 nm or shorter essential for realizing a full-color display and useful as an organic light emitting material or the like of a high melting temperature of 200°C or higher withstanding Joule heat generated upon applying a voltage thereto for use in an organic electroluminescent device. SOLUTION: The substituted ethynyl gold-nitrogen-containing heterocyclic carbene complex is represented by formula (1) wherein L represents a nitrogen-containing heterocyclic carbene ligand; and S represents an alkylmercapto group, an arylmercapto group, an alkylsulfonyl group or an arylsulfonyl group.
