摘要：
The invention relates to a diaphragm (1) for an ultrasonic transducer having a diaphragm body (2) which is made of metallic material and is provided on an outer surface region (5; 8) with a coating (10). In order to make it possible for the diaphragm surface to be provided with a particularly damage-resistant coating, the coating (10) has a transparent form such that the surface region (5; 8) of the diaphragm body (2) is visible through the coating (10).
