Abstract
A windproof lighter includes a windshield (44) with openings (443,444) facing the striker (43) and over the flame and nozzle area, edges on the openings, and rounded sides or flanges on the edges around the nozzle on the top edge of the butane well (3, 41), so that it is windproof by reducing the chance of flame extinguishment and is also scratch-proof and embodies simplification of construction. A shield (31) cover is provided over the windshield to prevent direct contact of the user with the windshield.
