    摘要: The present invention relates to an electric detonator containing no primary charge or igniting charge, having a simple structure, and capable of directly igniting a base charge of secondary explosive. A detonator of the present invention includes a cylindrical tube closed at one end, a base charge contained in the tube near the closed end thereof, and an ignition device inserted from an open end of the tube and accommodated near the open end. The ignition device is a semiconductor bridge device including a laminate layer and electrode pads. The laminate layer includes layers of a reactive metal and a reactive insulator. The base charge is, for example, pentaerythritol tetranitrate.
