PROBLEM TO BE SOLVED: To provide a pipe for providing a heat exchanger excellent in heat exchange efficiency from a different viewpoint from a conventional method. SOLUTION: A heat exchanging pipe 1 is substantially constituted into a planar shape by bending a pipe consisting of a specified material ( the metal of aluminum, for example, or the like ) into a serpentine shape ( concretely a meandered shape ). The heat exchanging pipe 1 has main parts 3 and bending parts 5 alternately and continuously and is flattened so that a clearance generated between at least one main part 3 and an other main part 3 adjacent in the direction across the longitudinal direction is reduced.
