To provide a transmission antenna for remote wireless detonation system by which all wireless primer detonators loaded to an entire working face can stably receive magnetic field energy even when the energy of the magnetic field is small and excellently prevent the antenna coating film from being damaged due to scattering stones.

The transmission loop antenna 2, which transmits magnetic field energy generated through remote control to wireless primer detonators 6 loaded to a working face 12 to detonate the wireless primer detonators 6, is closely placed over the entire circumference of a wall face of a hollow place to form the working face 12.
