Beschreibung
Zusammenfassung:	The present invention further improves the accuracy of measuring the viscosity of ink compositions. This ink composition is for forming a functional layer in an organic photoelectric conversion element and has an electron spin concentration per 1 L of volume of not more than 2501016. The ink composition may be an ink composition comprising a solvent and a p-type semiconductor material. The ink composition may be an ink composition in which the p-type semiconductor material contains a polymer compound that has an electron spin concentration per 1 g of weight of not more than 701016. The ink composition may be an ink composition in which the solvent comprises at least one organic solvent and the p-type semiconductor material contains a π-conjugated polymer compound that contains a donor constituent unit and an acceptor constituent unit.
