PROBLEM TO BE SOLVED: To quantitatively evaluate a degree of deterioration in a polymer material with high sensitivity, irrespective of a kind and a form of the polymer material. SOLUTION: A carbonyl group 11 is chemically modified by making a reagent 12 reactive with the carbonyl group 11 act selectively on the carbonyl group 11 generated on a surface 101 of the polymer material 10 in accompaniment to the deterioration of the polymer material 10, and a reaction product 13 of the carbonyl group 11 with the polymer material 10 is thereby generated on the surface 101 of the polymer material 10. A compound 141 derived from the chemically modified carbonyl group 11, i.e. the reaction product 13 is quantitatively determined by analyzing the polymer material 10 after the carbonyl group 11 reacts with the polymer material 10, by a pyrolysis gas chromatography, and an amount of the compound 141 is regarded as an amount of the carbonyl group 11 to serve as a basis of determining the deterioration of the polymer material 10.
