    • In an electrical fuse element (1), comprising a substrate (2) with contacts (11) arranged on two opposite sides of the same, between which contacts there runs a fusible conductor (3) which is produced in a laminating process and is connected electrically conductively to the contacts (11), the fusible conductor (3) is covered at least in the region in which the current-breaking operation proceeds by a pasty composition solidifying in a thermal process to form a mechanically stable layer (8), vitrifying in particular at least on one surface. Alternatively the covering of the fusible conductor (3) in the above-mentioned region is formed by a pasty composition which solidifies to a porous state and which for its part is covered by at least one further, mechanically stable layer and is closed from the outside.
