PROBLEM TO BE SOLVED: To improve heat exchange efficiency simultaneously with reducing flowing resistance. SOLUTION: Flat high-temperature-side elements 20 allowing high-temperature air to pass therethrough and flat low-temperature-side elements 30 allowing low- temperature air to pass therethrough are alternately stacked with each other. The air of the high-temperature-side elements 20 and the air of the low-temperature-side elements 30 pass in the orthogonal directions to each other to exchange the heat of the high-temperature air with that of the low-temperature air. Each high- temperature-side element 20 and each low-temperature-side element 30 are each provided with an element body 40 having end face plates 41 positioned in the both sides in the width direction and a guide plate 42 continuously provided with the end face plates 41 along the flow direction of the air, and a partitioning plate 50 provided close to one end face plate 4. Each high-temperature-side element 20 and each low- temperature-side element 30 are formed with hollow confluence parts 45, so that the air is mixed inside each high-temperature-side element 20 and each low-temperature-side element 30. The confluence space 45 is formed by punching out the end plates 41 and the guide plates 42 in the width direction and the width-directional end faces are closed by the partition plates 50.
