A linear dimension (L3) of the protruding portion in an air flow direction is larger than a plate thickness (L4) of the tube body portion. Each outer fin (5) is joined to both an upstream-side tube (31) and a downstream-side tube (21), which are arranged adjacently in the air flow direction. In the upstream-side tube, the protruding portion is connected to an upstream-side end portion of the tube body portion in the air flow direction.
