An electronic detonation device with a dual antenna for a blasting system is proposed. The electronic detonation device includes: an electronic detonator; a wireless communication module, and a wire part connecting the electronic detonator to the wireless communication module. The wireless communication module includes a first antenna part positioned in an upper portion therein and a second antenna part positioned in a lower portion therein. Accordingly, regardless of a placement direction of the wireless communication module on the ground, stable wireless communication is performed, thereby improving blasting accuracy.
