A stacking-type, multi-flow, heat exchanger includes heat transfer tubes and outer fins stacked alternatively. Each heat transfer tube is formed by connecting a pair of tube plates, and each heat transfer tube includes a raised portion fixing the pair of tube plates to each other. The raised portions are formed by elongating or raising a portion of the pair of tube plates substantially simultaneously at a position at which a pair of holes, each of which is formed through one tube plate beforehand, are aligned. Complicated steps, such as inserting a raised portion into a hole, are not necessary. The number of types of tube plates also may be reduced. Moreover, the efficiency of assembling a heat transfer tube when fixing a pair of tube plates to each other may be significantly increased.
