Abstract

1. An electric blastic cap comprising a pyrotechnic composition initiated by a resistive heating element of the type consisting of a printed circuit, characterized in that this printed circuit has a high accuracy such that at least one filament has a width ranging from 5 to 20 mu m thus presenting an ohmic value greater than 80k OMEGA/cm**2, and engraved by electrolytic or ionic machining from a masked sheet metal.
