Abstract: Provided are: a thermal stabilizer composition which does not generate an odor of a phosphorus-based antioxidant; and a synthetic resin composition comprising the same. The thermal stabilizer composition comprises: 100 parts by mass of a phosphorus-based antioxidant having a phosphite structure; and 0.001 to 10 parts by mass of a phenolic antioxidant having a substructure represented by the following Formula (1): (wherein, R1, R2, R3 and R4 each independently represent a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms; a represents an integer of 0 to 2; and, when a is 2, plural R3s are optionally the same or different).
