Abstract
A detonator pellet includes a composite insulating member made of a synthetic resin or a ceramic material, two wires being embedded during manufacture of the member which wires extend in and, respectively, on surfaces of a central part of the insulating member so that the wires, in this way, are supported so well that an ignition bridge can be directly attached to the ends of the wires by soldering, welding or bonding.
