Abstract
A heat transfer bodyis prepared. The heat transfer bodyforms an inner spacefor existence of one of a higher-temperature fluid or a lower-temperature fluid. The heat transfer bodyconstitutes a heat exchanger, and is formed of a copper material as a wall surrounding the inner space. In the wall, a flow path through which the other of the higher-temperature fluid and the lower-temperature fluid flows is formed. By LMD treatment, an LMD layer is formed directly on an outer circumferential surfaceof the heat transfer body. In the LMD treatment, a metal material is supplied to a supply position on the outer circumferential surface, and the supply position is irradiated with laser light to form an LMD layer. An energy density of the laser light is set to melt both the metal material and the outer circumferential surface
