A mobile body corrosion measuring apparatus having a corrosion sensor installed in at least one portion of a mobile body, the corrosion sensor measuring a corrosion state at the portion and outputting corrosion data; a vehicle (mobile body) running speed sensor installed in the mobile body, the running speed sensor measuring a running speed of the mobile body and outputting the running speed data; and a data collection unit that acquires the corrosion data from the corrosion sensor and the running speed data from the vehicle speed sensor at the same time and collects the corrosion data and the running speed data with the corrosion data and the running speed data associated with each other. Due to above structure, a corrosion state specific to the mobile body can be accurately measured.

An object of the present invention is to provide an exhaust gas purification catalyst which can minimize the separation of the catalyst layer due to heat and vibration, can suppress thermal deterioration of the catalytic substance, and can exhibit excellent purification capabilities under severe conditions. Specifically, the present invention relates to an exhaust gas purification catalyst wherein an undercoat layer comprising a heat-resistant inorganic oxide having an oxygen-absorbing substance added thereto is formed on a surface of a metallic carrier, and a catalyst-carrying layer is formed on the undercoat layer.
