A damping valve includes an annular valve seat, a valve body, an actuator for driving the valve body and a valve case including a valve hole into which the valve body is slidably inserted. The valve body includes a valve main body and a shaft for transmitting a thrust force of the actuator to the valve main body. The valve main body includes a flange partitioning the interior of the valve hole into a valve seat side chamber and an opposite valve seat side chamber, a shaft portion extending from the flange and a valve head to be seated on and lifted from the valve seat. The valve seat side chamber and the opposite valve seat side chamber communicate via a communication passage and the valve seat side chamber and the flow path communicate via a throttle passage.
