Detonators are mainly used for industrial explosives (industrial explosives) such as dynamite, slurry, and AN-FO. Explosives such as dynamite only burn when ignited with a match, but do not explode. They must be detonated using a detonator. A detonator consists of a highly sensitive primary explosive such as mercury or lead nitride, and a base charge such as tetryl. When the primary explosive is ignited, the base charge increases the explosive force, which detonates the explosive more powerfully. In the narrow sense, industrial detonators are detonators that are ignited by a fuse, but in the broad sense, they are a general term for both these and electric detonators. There are three types of detonators, No. 3, No. 6, and No. 8, depending on the amount of explosive contained, and No. 6 (0.85g of explosive) is usually used. Depending on the tube body, there are copper detonators, iron detonators, and aluminum detonators.

おもにダイナマイト,スラリー,AN-FOなどの工業爆薬 (産業火薬類) に利用される雷管。ダイナマイトなどの爆薬はマッチで点火しても燃焼するだけで爆発しない。これらは雷管を用いて起爆しなければならない。雷管は雷汞 (らいこう) または窒化鉛など感度の高い起爆薬と,テトリールなどの添装薬から成り,起爆薬が点火により起爆すると添装薬がその爆力を強め,これによって爆薬を強力に起爆させる。狭義の工業雷管は導火線により点火する雷管をいい,広義にはこれと電気雷管の両者を総称する。内容薬量により3号,6号,8号雷管があり,通常6号 (薬量 0.85g) が用いられ,管体により銅雷管,鉄雷管,アルミニウム雷管がある。
