The present invention provides an organic compound represented by general formula [1] described in claims. In general formula [1], Ar 1 and Ar 2 are each independently selected from an aryl group having 6 or more and 18 or less carbon atoms and a heteroaryl group having 3 or more and 15 or less carbon atoms. In general formula [1], R 1 to R 3 are each a hydrogen atom or a substituent. R 4 is an electron-withdrawing substituent. X 1 is oxygen or sulfur. Y 1 to Y 3 are each independently selected from a carbon atom and a nitrogen atom.
