An exhaust heat recovery system (10) includes: an exhaust heat exchanger (18) that is communicated with a catalytic converter (16) through an exhaust gas pipe (14A), and that recovers exhaust heat into a coolant; and heat transfer restriction means (50) provided between the catalytic converter (16) and the exhaust heat exchanger (18). The heat transfer restriction means (50) includes a heat insulator (56) disposed between a first exhaust gas pipe (52) and a second exhaust gas pipe (54) that constitute the exhaust gas pipe (14A), and. restrains a released heat from the catalytic converter (16) from reaching the exhaust heat exchanger (18).
