To provide a low cost radio detonation system.SOLUTION: A radio detonation system 1 includes a primer detonator 10, and a power feeding device 30 for supplying driving energy to the primer detonator 10. The primer detonator 10 includes a reception coil 12 for receiving the driving energy transmitted from the power feeding device 30, and a power storage element 26 for charging the received driving energy. The primer detonator 10 further includes a primer detonator side control circuit 21 for transmitting a charge completion signal when charging of the power storage element 26 is completed, and a light emitting element 14 for emitting light based on the charge completion signal. The power feeding device 30 includes an electricity transmission coil 32 for transmitting the driving energy in electromagnetic induction type. The power feeding device 30 further includes a light receiving element 33 for detecting light emitted by the light emitting element 14, and a power feeding device side control circuit 35 for recognizing charge completion of the power storage element 26 based on the signal from the light receiving element 33.SELECTED DRAWING: Figure 6 【課題】低コストの無線起爆システムを提供する。【解決手段】無線起爆システム１は、起爆雷管１０と、起爆雷管１０に駆動用エネルギーを供給する給電装置３０を有する。起爆雷管１０は、給電装置３０から発信された駆動用エネルギーを受信する受信コイル１２と、受信した駆動用エネルギーを充電する蓄電素子２６を有する。さらに起爆雷管１０は、蓄電素子２６の充電が完了した際に充電完了信号を発する起爆雷管側制御回路２１と、充電完了信号に基づいて光を発する発光素子１４を有する。給電装置３０は、駆動用エネルギーを電磁誘導方式で発信する送電コイル３２を有する。さらに給電装置３０は、発光素子１４が発する光を検知する受光素子３３と、受光素子３３からの信号に基づいて蓄電素子２６の充電の完了を認識する給電装置側制御回路３５を有する。【選択図】図６
