A heat exchange tube is constructed by forming, on a cylindrical tube peripheral wall, a plurality of projecting portions which project to an inside of the tube peripheral wall, and which are formed by pushing. The plurality of projecting portions are formed, respectively, into conical shapes across a tube axis, and are arranged along virtual spirals on the tube peripheral wall. Accordingly, it is possible to provide a heat exchange tube which facilitates formation of a plurality of projecting portions with the thickness hardly changed and without formation of protruded portions, and which is capable of contributing to enhancement of heat exchanging efficiency.
