1. A thermoplastic resin composition, comprising:
a thermoplastic resin;
a phosphoric acid ester compound (A) represented by the following general formula (1):

OG Complex Work Unit Chemistry
wherein R1 to R4 each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 9 carbon atoms, and R5 represents an alkylidene group having 1 to 4 carbon atoms;
a fatty acid sodium salt (B) represented by the following general formula (2):

OG Complex Work Unit Chemistry
wherein R6 represents a group introduced from an aliphatic organic acid having 7 to 30 carbon) atoms; and
a phosphite compound (E) represented by the following general formula (3):

OG Complex Work Unit Chemistry
wherein R7 and R8 each independently represent an alkyl group having 1 to 40 carbon atoms or an aryl group having 6 to 40 carbon atoms;
wherein an amount of the phosphoric ester compound (A) represented by the general formula (1) is 0.001 to 10 parts by mass based on 100 parts by mass of the thermoplastic resin,
wherein a ratio of the amount of the phosphoric acid ester compound (A) represented by the general formula (1) and an amount of the fatty acid sodium salt (B) represented by the general formula (2) is in the range of (B)/(A)=0.55 to 2.0 by mass ratio, and
wherein the thermoplastic resin composition does not comprise a petroleum resin.
