という結果が得られた。An electrical delay detonator to which such an electronic technology is applied can obtain a detonator with significantly higher accuracy in second time than a delay detonator using a delay agent, but its structure is composed of a complicated and fine electric circuit. Therefore, it has been found that there is a problem in impact resistance during handling and practical use. In other words, if an electrical delay detonator is installed in explosives such as dynamite and rocks are destroyed, for example, when an explosion occurs in the blast hole in the previous stage, the detonator loaded in the blast hole in the next stage receives extremely severe impact. However, it has been found that there is a problem in that the electrical delay element has some abnormality and blasting is unsuccessful. However, regarding this impact resistance, Japanese Patent Publication No. 56-26
Nothing is touched in JP-A No. 228, and in JP-A-54-43454, a method of embedding in an embolus is adopted.
In JP-A-57-35298, it is described that "a material such as an epoxy potting material, a material having low hardness, and a synthetic rubber material having impact resistance are enclosed." Therefore, according to our experiments, it was found that the epoxy resin potting and the one filled with the soft rubber cause a malfunction and a malfunction due to the impact.

It is possible to have an effect against external impact and blasting impact.
