1. A discrete fuse element for protecting a current consumer, comprising:
a first terminal point;
a second terminal point;
a fusible material, which melts at a predetermined temperature, between the first and the second terminal points, which is configured to establish, in the non-molten state, an electrically conductive connection between the first and the second terminal points; and
an assisting means between the first and the second terminal points, configured to assist in removing the fusible material in the molten state from an area between the first and the second terminal points, wherein the fusible material is deposited on a surface of a carrier, and the assisting means includes a layer of solder stop resist which exhibits a property of repelling the fusible material.
