<P>PROBLEM TO BE SOLVED: To provide a fin tube having high durability and achieving high heat exchanging efficiency. Ž<P>SOLUTION: This fin tube FT1 comprising a metallic tubular body 1, and a metallic fin 2 disposed at an outer circumference of the tubular body 1, further comprises a coating layer 3 made of an anticorrosive material, covering an outer peripheral face of the tubular body 1, and disposed in a state that at least a part of a metallic face of the fin is exposed to the external, the tubular body 1 and the fin 2 are kept into contact with each other without through the coating layer 3, or integrally connected with each other. Preferably, the fins 2 are provided with through-holes 22 in which a part of the coating layer 3 enters, and parts 30 adjacent to each other through each fin 2, of the coating layer 3 are integrally connected through the part entering into the through-hole 22.
