PROBLEM TO BE SOLVED: To provide a heat exchanger having a shape/structure capable of efficiently heating liquid in a fluid flow path.SOLUTION: Approximately S-shaped loop (SLTE) is formed at an approximately center part (C); an approximately spiral-shaped wound tube (STE) is formed on the outer periphery of the loop (SL). A liquid inflow port (12) and a liquid outflow port (13) are arranged so that each of the ports faces a side part (S)'s one direction, where the ports' directions are the approximately same direction or directions approximately opposite to each other. The loop (SLTE), the wound tube (STE), the liquid inflow port (12), and the liquid outflow port (13) are arranged substantially on the same plane. The wound tube (STE)'s cross section is formed in an approximately elliptical shape with an oblateness of 30 to 70%. Adjacent side parts (S) of respective tubes (T) constituting the wound tube (STE) are fixed by using heat welding.SELECTED DRAWING: Figure 1 【課題】流体流路内の液体を効率よく加温できる形状・構造を有する熱交換器を提供すること。【解決手段】略中心部（Ｃ）に、略Ｓ字状のループ（ＳＬＴＥ）を形成し、当該ループ（ＳＬ）の外周に略スパイラル状の巻回チューブ（ＳＴＥ）を形成している。液体流入口（１２）と液体流出口（１３）は、略同一または略反対の側部（Ｓ）の一方向に向けて配置し、前記ループ（ＳＬＴＥ）、前記巻回チューブ（ＳＴＥ）、前記液体流入口（１２）及び前記液体流出口（１３）は、実質的に同一平面上に配置している。前記巻回チューブ（ＳＴＥ）の断面は、略楕円状に形成し、当該略楕円の偏平率は、３０〜７０％である。前記巻回チューブ（ＳＴＥ）を構成する各チューブ（Ｔ）の隣接する側部（Ｓ）を熱溶着により固定した。【選択図】図１
