PROBLEM TO BE SOLVED: To provide a tube for a heat exchanger which can suppress deformation caused by the pressure of fluid, and can prevent damage caused by a collision of a small stone or the like.SOLUTION: An end part P1 of a tube 100 for a heat exchanger at one side in a cross section vertical to a longitudinal direction of the tube is formed into a double wall in which a part of an outer wall part 120 and a part of an inner wall part 110 are overlapped on each other, the other side end part P2 is formed into a single wall composed of only a part of the outer wall part 120, and a first space SP1 formed inside the inner wall part 110 and a second space SP2 formed inside the outer wall part 120 being outside the inner wall part 110 are arranged in alignment.SELECTED DRAWING: Figure 2
