Eine Elektrodenanordnung zur Erzeugung von Stoßwellen weist einen Behälter mit einem Übertragungsmedium darin auf, wobei an zwei gegenüberliegenden Behälterseiten Elektroden von außen in den Behälter hineinreichen. Die Elektrodenenden der Elektroden weisen einen Abstand zueinander auf und sind im Wesentlichen abgeflacht und aufgeraut zur besseren Zündung. Zusätzlich können sie noch zumindest bereichsweise eine Isolierung aufweisen.The assembly (11) comprises a container (12) including a transfer medium (15), and two electrodes (25a, 25b) extending on two opposite sides of the container from the outside into the container, where ends (27a, 27b) of the electrodes are spaced apart from each other and are flattened perpendicular to their longitudinal extension. The electrode ends are roughened with a micro-roughness and depressions of less than 100 microns. An insulation part is formed around some areas of the electrodes. The insulation part is 1-5 mm shorter than the height of the electrode ends.

The insulation part is 1-5 mm shorter than the height of the electrode ends. The insulation part in the longitudinal extension of the electrodes has different thicknesses and/or made of different materials. A front area of the insulation part extending close to one of the electrode ends is made of a mechanically more stable and resilient material, where the rear portion of the insulation part is made of plastic. The front part of the insulation is formed towards the end of the electrode, a
