To provide an evaluation method enabling evaluation of stress applied to bonding, which is hardly detected through Raman spectroscopy.SOLUTION: The evaluation method is provided comprising: using, for a rubber test piece, an infrared absorption spectrum obtained in a condition in which tensile force is not applied to the rubber test piece and an infrared absorption spectrum obtained in a condition in which tensile force is applied to the rubber test piece and calculating a shift quantity of a peak in the condition in which the tensile force is applied to the rubber test piece; and evaluating stress in the rubber test piece from the shift quantity of the peak.SELECTED DRAWING: None 【課題】ラマン分光法では検出が困難な結合にかかる応力を評価できる評価方法を提供する。【解決手段】ゴム試験片に対し、引張力を印加していない状態で得られた赤外吸収スペクトルと、引張力を印加した状態で得られた赤外吸収スペクトルとを用いて、引張力を印加した場合のピークのシフト量を算出し、前記ピークのシフト量から、前記ゴム試験片中の応力を評価する評価方法に関する。【選択図】なし
