PROBLEM TO BE SOLVED: To provide an outdoor structure equipped with a corrosion detector capable of preventing injury from salt, while monitoring the change of injury from salt with the passage of time, at all times. SOLUTION: The corrosion detector 10A, provided in the outdoor structure, includes a corrosion sensor 110 for monitoring corrosion environment, an ammeter 115 for measuring the corrosion current produced in the corrosion sensor 110 and a variable resistor 11 for altering the corrosion current; and when the corrosion environment is measured, the variable resistor 11 is changed so that the corrosion current maintains substantially a constant value (e.g., 100 nA).
