FIELD: means for initiation at blasting and intended for intensifying the transmission of initiating signal from various electric and non-electric sources. SUBSTANCE: detonator is made in the form of a tubular housing with a bottom on one end and open end face on the other for placing of the device for transmission of actuating signal. The bottom of the housing carries an explosive charge and a buffer element engageable with it and made in the form of a disc with an interference fit. The buffer element can have at least one opening and be provided with a membrane or net. Besides, the detonator can be furnished with a delay unit in the form of a bush retarding compound installed between the signal transmitting device and buffer element. EFFECT: enhanced reliability. 5 cl, 9 dwg
