The invention relates to a multipolar cannula (10, 10'), comprising: a cannula tube (12), which has a distal end (14) and a proximal end; a first electrode (22); and at least one second electrode (24, 26, 28a, 28b, 28c). The cannula tube (12) has a cannula tube body (18) and a coating (20), which electrically insulates the first and the second electrode (22, 24) from one another. The distal end (12) of the cannula tube has a distal tip (16), and an attachment is arranged on the proximal end, which attachment has an electrically contacting connection point for the electrodes (22, 24). The electrically insulating coating (20) and at least the second electrode (24, 28a, 28b, 28c) are applied to the cannula tube body (18) in a thin-film process.
