In each space 41, a plurality of outer fins 43 are stacked to be arranged, and partition boards 45 are individually arranged between the outer fins 43. At least on edges of each partition board 45 on sides of tank formation portions 37, bent portions 47 and 49 bent in the stacking direction of the tube sheets 29 are formed. Moreover, the position in the stacking direction of an edge 61a of a partition board 61 on a side of the tank formation portions 37, 37A, or 37B is different from the position in the stacking direction of a joint portion of the tank formation potions 37, 37A, or 37B, respectively. <IMAGE>
