PROBLEM TO BE SOLVED: To provide an anticorrosive method of the inside of a steel structure having a semi-enclosed structure and an anticorrosive apparatus capable of preventing the corrosion of a steel material inside of a steel-made structure of the semi-enclosed structure at a low cost by using a dehumidifier without painting the steel material. SOLUTION: The semi-enclosed structure comprises a plurality of rooms R1 to R5 formed by partitioning an inside space with a partition, the dehumidifier 3 is provided to the inside or the outside of the steel-made structure of the semi-enclosed structure communicating the rooms to each other by a manhole 5 provided to the partition 2, the air inside of each room and the air incorporated from the outside is supplied to the dehumidifier 3, the dry air manufactured by the dehumidifier is directly introduced to each room from a horizontal hole 6 provided to a duct or the horizontal hole 6 and an exhaust port 7 of the end section through the duct 4 to prevent the corrosion of the inside of steel-made structure of the semi-enclosed structure by maintaining relative humidity in the room of the inside of the steel-made structure at a critical value or below.
