A novel platinum complex useful as a material for luminescent elements satisfactory in luminescent properties and luminescent efficiency; and a novel luminescent material utilizable in various fields. The platinum complex is represented by the following general formula (1): [Chemical formula 1] (1) wherein any two of rings A, B, C, and D each represents an optionally substituted nitrogenous heterocycle and the remaining two each represents an optionally substituted aryl or heteroaryl ring, provided that rings A and B, rings A and C, or/and rings B and D may form a fused ring; any two of X1, X2, X3, and X4each represents a nitrogen atom coordinating to the platinum atom and the remaining two each represents carbon or nitrogen; Q1, Q2, and Q3 each represents a bond, oxygen, sulfur, or a divalent group; and any two of Z1, Z2, Z3, and Z4 each represents a coordinate bond and the remaining two each represents a covalent bond, oxygen, or sulfur. The luminescent element employs this platinum complex.
