METHOD FOR PRODUCING A PRICKING ELEMENT

摘要

The present invention provides a process for producing a lancing element in which a flat-shaped member is formed from a flat material by applying a mask and allowing an etching agent to act upon it, wherein at least a part of the flat-shaped member is shaped as a tip. The mask is provided with a shaping area for the tip to be formed and with a screening area which extends distally beyond this shaping area to prevent the tip from being etched off at the front. A sharp tip is exposed by laterally undercutting the side flanks of the shaping area and screening area.
