ABSTRACT:
A heat exchanger tube41includes: a first cover layer44provided on an outer side of a tube main body42to partly or completely cover a tube main body42; and a second cover layer45provided on an outer side of the first cover layer44to partly or completely cover the first cover layer44.The first cover layer44is formed by overlay-welding a material higher in ductility than the second cover layer45to the tube main body42.The second cover layer45is formed by overlay-welding a material higher in hardness than the first cover layer44to the first cover layer44.
