Electrode arrangement (3) comprises a first component for cutting away an electrically non-conducting material (1) and a second component for depositing an electrically conducting substance (7) onto the non-conducting material. An independent claim is also included for a method for the electrical discharge machining of an electrically non-conducting material. Preferred Features: The two components are chemically and/or physically different compounds, preferably metals. The first component is an eroding electrode (3a) and the second component is a depositing electrode (3b). Elektrodenanordnung (3) für die funkenerosive Bearbeitung eines elektrisch nichtleitenden Materials (1), die einen ersten Bestandteil (3a) zum Abtragen des elektrisch nichtleitenden Materials (1) und einen zweiten Bestandteil (3b) zum Abscheiden einer elektrisch leitenden Substanz (7) auf dem elektrisch nichtleitenden Material (1) aufweist.
