1-23. (canceled)
A hydraulic system control plate, comprising:
- at least one first layer, at least one second layer and at least one inner layer disposed between the first layer and the second layer,
- the at least one inner layer having at least one through-opening which is delimited, on at least one part of its extension situated in a surface of the inner layer, by the first layer and the second layer in the direction perpendicular to the surface of the inner layer,
- one, several or all of the layers comprising aluminium, and
- at least two adjacent ones of the layers or all of the layers, which are adjacent to each other in pairs, being soldered together at least in regions.

A method for producing a hydraulic system control plate,
- solder being applied on at least one plate of a base material,
- at least one layer being produced from the at least one plate of the base material,
- at least three layers comprising the at least one first layer being disposed one on the other such that all the directly adjacent ones of the layers abut one on the other via at least one surface which is coated with solder,
- and the layers which are disposed one on the other being heated to a melting temperature of the solder.
