A fourth embodiment of the detonator 1 of the present invention will be described with reference to FIG. The detonator 1 has an insulating coating layer 3
The conductive member 8 integrally disposed on the insulating coating layer 3
Is arranged in a meandering shape along the longitudinal direction of the pipe between the vicinity of the outer peripheral surface and the inner surface in contact with the pipe main body 2, whereby the electric discharge at the time of lightning strike can be performed without the need for a separate conducting means. It is possible to disperse the lightning current due to the electric current to the tube body 2 and to contribute to the flexibility of the tube body 2. In the structure shown in FIG. 4, adjacent two meandering conductive members 8 are arranged in a staggered manner, and one of the conductive members 8 is an insulating coating layer in the longitudinal direction of the pipe. 3 is arranged so as to be located in the vicinity of the outer peripheral surface of 3, so that the conductive member 8 located in the vicinity of the outer peripheral surface of the insulating coating layer 3 becomes substantially continuous in the longitudinal direction of the pipe.
As described above, the lightning current dispersion function can be improved, and the number of the conductive members 7 may be one.

Since the detonator of the present invention is constructed as described above, it is an insulating member integrally provided with a conductive member that covers the outer peripheral region of the tube body of the detonator due to discharge during lightning strike. Although the conductive coating layer will be damaged, most of the lightning current due to discharge at the time of a lightning strike is led from the conductive member to the ground through the conductive joint through the joint for connection and to one point on the pipe body. Since the energy is not concentrated, the influence on the pipe body is minimal.
