An exhaust heat recovery apparatus comprising: a bypass part having a main exhaust gas flow passage into which an exhaust gas of an internal combustion engine is introduced; a heat exchange part disposed adjacent to the bypass part and having a heat exchanger for exchanging heat between the exhaust gas and a heat carrier; a gas flow-in port disposed upstream of the heat exchange part in an exhaust gas flow, the gas flow-in port causing the exhaust gas to flow in the heat exchange part from the bypass part; a gas flow-out port (12, 512) disposed downstream of the gas flow-in port in the exhaust gas flow, the gas flow-out port (12, 512) causing the exhaust gas to flow out to the bypass part from the heat exchange part; and a valve including a rotatable rotation shaft, a valve body having one end fixed to the rotation shaft, and an actuator for rotating the rotation shaft, wherein a rotating end of the valve body is disposed downstream of the gas flow-out port (12, 512) in the exhaust gas flow, and the valve is provided in the main exhaust gas flow passage of the bypass part, wherein a heat exchange flow passage, through which the exhaust gas flows into the heat exchange part from the main exhaust gas flow passage through the gas flow-in port and returns to the main exhaust gas flow passage from the heat exchange part through the gas flow-out port (12, 512), is formed, and on a most downstream side of the heat exchange flow passage, a return flow passage (17, 517), in which the exhaust gas flows in a direction opposite to a direction of the exhaust gas flow in the main exhaust gas flow passage, is provided. a bypass part having a main exhaust gas flow passage into which an exhaust gas of an internal combustion engine is introduced; a heat exchange part disposed adjacent to the bypass part and having a heat exchanger for exchanging heat between the exhaust gas and a heat carrier; a gas flow-in port disposed upstream of the heat exchange part in an exhaust gas flow, the gas flow-in port causing the exhaust gas to flow in the heat exchange part from the bypass part; a gas flow-out port (12, 512) disposed downstream of the gas flow-in port in the exhaust gas flow, the gas flow-out port (12, 512) causing the exhaust gas to flow out to the bypass part from the heat exchange part; and a valve including a rotatable rotation shaft, a valve body having one end fixed to the rotation shaft, and an actuator for rotating the rotation shaft, wherein a rotating end of the valve body is disposed downstream of the gas flow-out port (12, 512) in the exhaust gas flow, and the valve is provided in the main exhaust gas flow passage of the bypass part, wherein a heat exchange flow passage, through which the exhaust gas flows into the heat exchange part from the main exhaust gas flow passage through the gas flow-in port and returns to the main exhaust gas flow passage from the heat exchange part through the gas flow-out port (12, 512), is formed, and on a most downstream side of the heat exchange flow passage, a return flow passage (17, 517), in which the exhaust gas flows in a direction opposite to a direction of the exhaust gas flow in the main exhaust gas flow passage, is provided.
