This damping valve is provided with the following: a valve-seat member provided with a port; a valve element that opens and closes said port; a cylindrical spool that abuts against the side of the valve element facing away from the valve-seat member; a spool-retaining member around which the spool is fitted so as to be able to move axially; a ring that is fitted around the spool-retaining member and makes sliding contact with the inside surface of the spool; and a back-pressure chamber that is defined by the spool and the spool-retaining member and, via internal pressure, biases the spool so as to push the valve element towards the valve-seat member. The pressure inside the back-pressure chamber is made to act on the inside of the ring.
