PROBLEM TO BE SOLVED: To provide an ozone purifying device for a vehicle provided with a function capable of surely detecting deterioration of an ozone purifying catalyst caused by various kinds of factors such as deterioration due to sticking of foreign matter such as dust and deterioration due to SOx. SOLUTION: Ozone concentration CTO3U in air before passing the ozone purifying catalyst carried on a radiator 1 and ozone concentration CTO3L in air after passing the ozone purifying catalyst are detected. Based on the ozone concentration CTO3U and CTO3L, a deterioration degree of the ozone purifying catalyst is detected.
