The present disclosure relates to an electronic detonation device for a blasting system. The electronic detonation device include: an electronic detonator; a wireless communication module; an electric wire connecting the electronic detonator to the wireless communication module; and a communication module support in which the electric wire is stored in a wound state, with the wireless communication module positioned on an upper surface of the communication module support. The communication module support is provided with a pile part configured to be driven into a ground for fixation, so that the electronic detonation device enables stable communication reliability to be secured by orienting the wireless communication module toward the sky, thereby preventing malfunction during blasting and improving blasting accuracy.
