To provide a heat exchanger capable of suppressing stress concentration on a boundary part between a heat radiation part and a frame body, and a manufacturing method for a heat exchanger.SOLUTION: A heat exchanger comprises a heat radiation part with an open outer surface, and a frame body provided at both end parts of the heat radiation part, where the heat radiation part has a displacement adjustment part functioning as a spring element. The heat exchanger is manufactured by integrally molding the displacement adjustment portion functioning as the spring element with the heat radiation part and integrally molding the frame body on both end parts of the heat radiation part by a lamination molding method using metal materials.SELECTED DRAWING: Figure 1 【課題】放熱部と枠体との境界部への応力集中を抑止することができる熱交換器及び熱交換器の製造方法を提供すること。【解決手段】外面が開放された放熱部と、放熱部の両端部に設けられる枠体と、を備える熱交換器であって、放熱部は、ばね要素として機能する変位調整部を有する。熱交換器は、金属材料を用いた積層造形法によって、放熱部に、ばね要素として機能する変位調整部を一体成形するとともに、放熱部の両端部に枠体を一体成形することによって製造される。【選択図】図１
