PROBLEM TO BE SOLVED: To provide a modified graphene, a resin composite and a dispersion having a low defect concentration. SOLUTION: A modified graphene of the following formula (I) in which the intensity ratio (g / d) of Raman's G band and D band is 1 or more: Gr1-Ar1-X1- (Y1) n1 (I) [Gr1 is graphene. , Ar1 is an arylene group having 6 to 18 carbon atoms, X1 is a single bond, and carbon atoms in an alkylene group having 1 to 20 carbon atoms or an alkylene group having 1 to 10 carbon atoms are represented by -O-, -NH-,. A group substituted with a structure selected from -CO-, -COO-, -CONH-, and an arylene group, Y1 becomes a carbon atom in Ar1 when X1 is a single bond, and a carbon atom in X1 when it is not a single bond. Hydrogen, halogen, fluoroalkyl group with 1 to 6 carbon atoms, cyano group, nitro group, acyl group, amide group, vinyl group, carboxylic acid group, carboxylic acid ester group, phosphoric acid group, 3 to 6 carbon atoms to be bonded An atom or group selected from the alkylsilyl (ether) groups and siloxane groups of. n1 is an integer greater than or equal to 1. ] [Selection diagram] None
