PROBLEM TO BE SOLVED: To provide a hydrogen peroxide analyzer and a hydrogen peroxide analytical method capable of analyzing easily and high sensitively a micro amount of hydrogen peroxide in water. SOLUTION: A water specimen serving as an analytical object is introduced into the analyzer from a prescribed position A in a water treatment process by a sample collecting tube 12, the water specimen is supplied to a main analytical line including a hydrogen peroxide decomposing part 16 constituted of a column packed with a material having hydrogen peroxide decomposing ability, and a dissolved oxygen concentration measuring part 18, and is supplied to a sub-analytical line including the dissolved oxygen concentration measuring part 18, and measured values of dissolved oxygen concentration measured in the respective lines are input into a computing part 20 to calculate a hydrogen peroxide concentration in the water specimen.
