PROBLEM TO BE SOLVED: To provide a compact exhaust gas heat recovery device capable of suppressing overheating of a medium. SOLUTION: In this exhaust gas heat recovery device 1 constituted by arranging a heat exchange path 10 for exchanging heat of exhaust gas and the medium adjacent to a bypass path 4 detouring the heat exchange path 10 and providing a switching means 5 for switching the heat exchange path 10 and the bypass path 4, a thermal insulation member 7 is provided as a heat insulating means between the heat exchange path 10 and the bypass path 4 to form a heat insulating layer 8.
