The invention relates to a high reliable electronic ignition device, comprising a normal open switch, a movement mechanism, a temperature induction and control element formed by shape memory alloy, an electric blasting squib, a plurality of wires and a casing. The invention is characterized in that the temperature induction and control element formed by shape memory alloy controls the action of the movement mechanism; the normal open switch is closed when the movement mechanism acts, the circuit of the electric blasting squib is then switched on, the current runs through the wires and then reaches the electric blasting squib to excite the electric blasting squib. The invention has the advantages of greatly improved high reliability of the electronic ignition device due to the thermal excitation changed from pure electronic excitation, radical avoidance of error-sprinkle, relatively strong anti-fluctuation ability of external power supply, anti-interference ability of strong electromagnet, simple structure, extensive application in various automatic aerosol distinguishers, safety and reliability and long service life.
