PROBLEM TO BE SOLVED: To provide a laminated type evaporator capable of preventing heat conduction between adjacent refrigerant passages when refrigerant passes through tubes, and capable of reducing thickness of the tube. SOLUTION: A plurality of tube bodies 21 laminated alternately with cooling fins 22 are formed from first tubes 23 positioned in an upwind side of cooling air, and second tubes 24 positioned in a downwind side as different members, and tube members 23, 24 are arranged along a flow direction of the cooling air with a predetermined interval in between. By this, heat conduction is prevented by the interval between the first tube 23 and the second tube 24. Since the first tube 23 and the second tube 23 are different members, there are no constraint in thickness necessary for forming a portion between adjacent header parts as in a conventional one, and since drawing work of material for tube sheets 25, 26, 30, 31 is easy, thinning of the material can be realized.
