摘要： PROBLEM TO BE SOLVED: To provide an electronic type delay detonator having a high anti-shock characteristic against an explosion in which a plurality of explosives are loaded in an item to be broken and an explosion delay tinme is controlled in a high accurate manner during an explosion work for exploding these explosives in sequence. SOLUTION: There are provided an energy accumulation circuit 5 for accumulating electrical energy supplied from a blasting device, a first oscillator circuit 11 with a crystal oscillator element operated by the electrical energy accumulated in the energy accumulating circuit being applied as a reference value, a second oscillator circuit 13 having an anti-shock characteristic, and a time counting period making circuit 14 for use in making a time counting period by the second oscillator circuit in such a way that the time counting period may coincide with a reference period made by the first oscillator circuit. This electronic type delay detonator is also comprised of trigger signal generating circuits 31, 32 for outputting a trigger signal in reference to the time counting period under an operation of the second oscillator circuit and of an electrical discharging circuit 8 for discharging electrical energy responding against the trigger signal and accumulated in the energy accumulating circuit.
