    • Deflection (bend) in the length direction due to a difference in the heat expansion between two plate-like members, between which rows of heat transfer tubes are sandwiched, is reduced, and deflection (bend) of rows of heat transfer tubes is prevented. Two long plate-like members (11), in which a plurality of cutouts (12) along the longitudinal direction are provided in one side the widthwise direction, are provided, and each of the cutouts (12) includes two rectilinear sections (13) that extend in a direction perpendicular to the longitudinal direction axis of the plate-like members (11), and a semicircular section (14) that links one end of the rectilinear sections (13) together. The distance between the two rectilinear sections (13) along the lengthwise direction axis of the plate-like members (11) and the diameter of the semicircular section (14) is set so as to be greater than the diameter of the heat transfer tubes that are contained within the cutouts (12). Tongue sections (18) are provided both between adjacent cutouts (12) and between the cutouts (12) positioned at both end portions of the plate-like members (11) in the length direction and both side surfaces (17) of the plate-like members (11) in the lengthwise direction.
