Beschreibung
Zusammenfassung:	The present invention aims to produce a graphene/organic solvent dispersion liquid that is in a stably dispersed state and also unlikely to cause electrolysis of water. The present invention provides a graphene/organic solvent dispersion liquid including graphene dispersed in an organic solvent and having a value of (W2 - W1)/G in the range of 0.005 or more and 0.05 or less, wherein W1 and W2 are the water fractions measured at 130°C and 250°C, respectively, by the Karl Fischer's method and G is the solid fraction of the graphene.
