PROBLEM TO BE SOLVED: To provide an electric detonator plug which ensures regulated intervals between lead pins and elimination of accidental explosion caused by induction, and further facilitates production of the electric detonator plug perse and installation of the same in an electric detonator. SOLUTION: A predetermined insulation distance is held between an inner hull of a pin insertion hole 322 formed in a bottom wall 32 of a sealing metal attachment 3, for receiving the other lead pin 22, and the periphery of the lead pin, and an insulating header 1 rests on the outer surface of the bottom wall 32. A through hole 11 for receiving a thick collar 212 at the front end of a lead pin 21 and a closed-end hole 12 with an enlarged bottom, for receiving a thin collar 222 at the front end of the lead pin 22 are formed in the insulating header, and the thick collar 212 is fitted into the through hole 11 in a manner of being in contact with the outer surface of the bottom wall 32, while the thin collar 222 is fitted into the closed-end hole 12 with enlarged diameter at the bottom. Then, a sealing agent 4 is charged into the above-mentioned sealing metal attachment, to thereby produce an electric detonator plug.
