Summary:To suppress the deviation of thermal load in a plurality of internal flow paths while securing the rigidity of fins by using residual parts.SOLUTION: A heat exchanger includes a plurality of flat tubes 1 having a plurality of internal flow paths L formed along the tube axial direction, and fins 2 where a plurality of long-sized slits S into which the flat tubes 1 are inserted, respectively, are formed ranging from a first long-side part 21 extending in the longitudinal direction midway through a second long-side part 22 on the opposite side to the first long-side part 21, extending in the longitudinal direction, and whose residual parts ranging from terminal ends S1 of the slits S to the second long-side part 22 continue with each other in the longitudinal direction. The flow path cross section of one of the internal flow paths L of the flat tubes 1, located nearest to the second long-side part 22 side, is larger than the flow path cross section of the other located closer to the first long-side part 21 side than the internal flow path L.SELECTED DRAWING: Figure 2 【課題】残存部によりフィンの剛性を担保しつつも、複数の内部流路における熱負荷の偏りを抑制する。【解決手段】管軸方向に沿った複数の内部流路Ｌが形成された複数本の扁平管１と、長尺状をなし、扁平管１それぞれが挿し込まれる複数本のスリットＳが、長手方向に延びる第１長辺部２１から、この第１長辺部２１とは反対側で長手方向に延びる第２長辺部２２に至る途中まで形成されており、このスリットＳの突き当たり部Ｓ１から第２長辺部２２までの残存部が長手方向に連なっているフィン２とを備え、扁平管１の内部流路Ｌのうち、最も第２長辺部２２側に位置するものの流路断面が、この内部流路Ｌよりも第１長辺部２１側に位置するものの流路断面よりも大きくなるようにした。【選択図】図２
