Abstract: The invention relates to a high-voltage fuse comprising a tubular ceramic insulating member that is provided with at least one fusible element, an inner auxiliary cap which is placed on the insulating member and at least partly covers the outer surface of the insulating member in the front area of the insulating member, and an outer top cap that is placed on the auxiliary cap and at least partly covers the outer surface of the auxiliary cap. The insulating member is provided with at least one depression. The auxiliary cap is molded against the insulating member such that a positive connection to the insulating member is created in the depression. The auxiliary cap and the top cap are molded in the area of said depression in such a way that a positive connection is created.
