Abstract: The invention concerns a surface treatment electrode (11) to treat at least one object (1). It comprises at least one cavity (23) enclosing the object (1) to be treated during the treatment, having a geometry ensuring free movement of the object (1), this cavity (23) being delimited by a wall (24) comprising at least one opening (25) communicating the inside of the cavity (23) with a treatment solution (5) in which the electrode (11) is immersed during the surface treatment. The cavity (23) is substantially cylindrical and its diameter is approximately 50 to 100 micrometers larger than a maximum size of the object (1).
