To provide a heat exchanger that enables sufficient reduction in thickness, offers a high degree of freedom in design, and ensures heat exchange ability.SOLUTION: A heat exchanger comprises a heat medium inlet and a heat medium outlet. The heat exchanger comprises a resin sheet with a heat medium channel and a cover sheet. The cover sheet is constituted to satisfy either (1) or (2): (1) it comprises, in order from the resin sheet side, a heat-sealable polymer layer and a heat transfer layer, with the heat-sealable polymer layer provided in a portion of the heat transfer layer; and (2) it comprises, in order from the resin sheet side, a heat transfer layer and a heat-resistant resin layer, with the heat-resistant resin layer provided in a portion of the heat transfer layer. In the resin sheet, a portion of the channel-forming surface is open, or the channel is formed hollow inside.SELECTED DRAWING: Figure 1 【課題】十分な薄型化を図ることができ、設計の自由度が高く、且つ熱交換能が担保される熱交換器を提供する。【解決手段】熱交換器は、熱媒体流入口及び熱媒体流出口を有し、熱媒体の流路を有する樹脂シートと、被覆シートと、を備え、前記被覆シートは、下記（１）又は（２）のいずれかを満たす。（１）前記樹脂シート側から順に、熱融着性樹脂層と、伝熱層とを備え、前記熱融着性樹脂層は前記伝熱層の一部に設けられる。（２）前記樹脂シート側から順に、伝熱層と、耐熱性樹脂層とを備え、前記耐熱性樹脂層は前記伝熱層の一部に設けられる。樹脂シートは、流路を構成する面の一部が開放されているか、又は内部に流路が中空状に形成されている。【選択図】図１
