A porphyrazine derivative in which porphyrazine forms a condensed ring with thiophene and a skeleton of the thiophene has a functional group such as an alkyl group at position 2 has a high solubility in an organic solvent and exhibits a high crystallinity. Therefore, the porphyrazine derivative is suitably used in crystalline thin-film formation using a solution process. This provides a novel porphyrazine derivative and an intermediate thereof, which porphyrazine derivative has a high solubility in an organic solvent and is excellent in molecular orientation, a method for production of the porphyrazine derivative and the intermediate, and use of the porphyrazine derivative and the intermediate.
