A damping valve for a vibration damper includes a damping valve body with separate passage channels. The outlet orifices of the passage channels for a flow direction are connected to one another via a groove, which is covered by at least one valve disk and is bounded radially by at least one annular web on the radially inner side with respect to the center axis (A) of the damping valve and at least one annular web on the radially outer side with respect to the center axis (A) of the damping valve. The radially outer web has at least one first portion in which the support is configured as area support for the valve disk, and the radially outer web has at least one second portion in which the support is configured as line support for the valve disk.
