PROBLEM TO BE SOLVED: To produce a ketone from a secondary alcohol corresponding thereto with high yield and selectivity by using a small amount of a bromic acid or a salt thereof. SOLUTION: The ketone is produced by oxidizing the corresponding secondary alcohol in the presence of an oxidizing reagent composed of the bromic acid or the salt thereof and a reducing inorganic compound. The ratio of the bromic acid or the salt thereof is 0.45-0.9 equivalent based on hydroxyl group of the secondary alcohol. The secondary alcohol may be a cycloalkanediol or the like. The ratio of the reducing inorganic compound may be about 0.2-0.6 equivalent based on 1 equivalent of the bromic acid or the salt thereof. The reducing inorganic compound may be a sulfite, a hydrogensulfite, a pyrosulfite, a thiosulfate, etc. The concentration of the secondary alcohol in the reaction system may be >=5 wt.%.
