    摘要： A state determining apparatus for an exhaust gas purifier (6) is provided for accurately determining the state of the exhaust gas purifier including an adsorbent (7) for adsorbing hydrocarbons, including a deterioration of the adsorbent (7), in accordance with a temperature state in an exhaust system of an internal combustion engine (1). The state determining apparatus for an exhaust gas purifier is arranged in an exhaust system of the internal combustion engine for determining the state of the exhaust gas purifier including the adsorbent (7) capable of adsorbing hydrocarbons and moisture in exhaust gas. The state determining apparatus comprises a humidity sensor (22) arranged near the adsorbent (7) in the exhaust system for detecting the humidity within a bypass exhaust pipe (14), and an ECU (25) for determining a temperature state of the exhaust system and determining the state of adsorbent (7) in accordance with the humidity within the bypass exhaust pipe (14) detected by the humidity sensor (22) and the temperature state in the exhaust system detected by the ECU (25).
