摘要

A heat exchanger tube 41 includes: a first cover layer 44 provided on an outer side of a tube main body 42 to partly or completely cover a tube main body 42; and a second cover layer 45 provided on an outer side of the first cover layer 44 to partly or completely cover the first cover layer 44. The first cover layer 44 is formed by overlay-welding a material higher in ductility than the second cover layer 45 to the tube main body 42. The second cover layer 45 is formed by overlay-welding a material higher in hardness than the first cover layer 44 to the first cover layer 44.
