description	PROBLEM TO BE SOLVED: To provide an electronic delay type ignition device and an electric detonator which are safe because an accidental burst does not occur when a switching part is acted by an electronic timer for inspecting the ignition circuit of the electronic delay type ignition device, which realize high time precision that the precision at the time interval of initiation is within ±0.5 ms and whose detonative reliability is high. SOLUTION: The case that lead styphnate is used as an ignition powder 106 and that DDNP/KClO3is 50/50 is particularly favorable for the precision. The case that basic lead styphnate is used is most favorable because the precision is ±0.1 ms or less. When the invented ignition powder is used, blasting with precision and high reliability can be controlled as the precision within ±0.5 ms is achieved regardless of a standard time.
