Abstract: Disclosed is an antioxidant for a thermoplastic resin that provides an excellent oxidation-preventing effect to a thermoplastic resin and that has an excellent effect of preventing a change in color caused by nitrogen oxides. Specifically, a compound represented by any of General Formulae (2) to (4), particularly a compound in which R2 in the formulae is an alkyl group having 1 to 8 carbon atoms whose terminal on an oxygen atom side is linked with —CO—O—, is used as the antioxidant for a thermoplastic resin. Details of General Formulae (2) to (4) are as described in the description.
