Thermoplastic resin composition, molding material and molded body

The present invention provides a thermoplastic resin composition which contains: a compound (F) that is at least one compound selected from the group consisting of a macromonomer (A) represented by formula (1) and a copolymer (C) that contains a structural unit derived from the macromonomer (A); and a compound (G) that is represented by formula (2). (In formula (1), each of R0 to Rn independently represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group or a heterocyclic group; each of X1 to Xn independently represents a hydrogen atom or a methyl group; Z represents an end group; and n represents a natural number of 1 to 10,000.) (In formula (2), each of R0 to R4 independently represents an alkyl group having 1 to 5 carbon atoms; and R5 represents an alkyl group having 1 to 5 carbon atoms or a hydrogen atom.).
