。A return member is provided that conducts negative pressure in an intake pipe of an internal combustion engine or a signal negative pressure corresponding to the negative pressure in the intake pipe into a chamber formed by a negative pressure sensitive member and a case member, and acts to resist the negative pressure. A valve stem is fixed to the negative pressure sensitive member, a valve body is provided at the tip of the valve stem, and a valve seat is provided at the exhaust gas inlet of the lower wall of the body member in response to the negative pressure. In an exhaust gas recirculation valve that is configured to change the passage area for exhaust gas passing through the valve body and is provided with a bypass passage that communicates the intake pipe and the exhaust pipe, the exhaust gas passage area can be changed by the differential pressure before and after the valve body. An exhaust gas recirculation valve characterized by:
