PROBLEM TO BE SOLVED: To provide a heat exchanger tube excellent in heat exchange performance and a strong circumferential fin excellent in impact resistance to a flying stone or the like and causing no bending or the like in the bending work of the heat exchanger tube by enhancing the adhesion between the circumferential fin and a metallic pipe to improve the mutual heat conductivity, and to provide a heat exchanger tube capable of being set even in a narrow space while keeping excellent heat exchange performance with increased durability by enabling the bending work of the heat exchanger pipe with a small bending radius. SOLUTION: This heat exchanger tube is formed by spirally winding a steel-made strip fin member 3 having sacrificially corrosive anticorrosive plating layer 4 arranged on the whole surface on the circumferential surface of a metallic pipe 2 made of copper, aluminum, a copper-based alloy, or an aluminum-based alloy.
