Electric igniter and method of manufacturing same

Abstract

The present invention relates to an electric igniter including: a heat-generating body which generates heat by being electrified, an accommodation chamber in which the heat-generating body is disposed and exposed at the bottom surface, an explosive material being accommodated in the accommodation chamber, having a first layer in the heat generating body side and a second layer which is an upper layer of the first layer, the first layer formed by loading a first explosive material in a dry state, and the second layer formed by loading a second explosive material in a wet state.

1 . An electric igniter comprising: 
 a heat-generating body which generates heat by being electrified,    an accommodation chamber in which the heat-generating body is disposed and exposed at the bottom surface,    an explosive material being accommodated in the accommodation chamber, having a first layer in the heat generating body side and a second layer which is an upper layer of the first layer,    the first layer formed by loading a first explosive material in a dry state, and the second layer formed by loading a second explosive material in a wet state.    
   
   
       2 . The electric igniter according to  claim 1 , wherein the second explosive material comprises a fuel, an oxidizing agent and a binder.  
   
   
       3 . A method of manufacturing an electric igniter comprising a heat-generating body that generates heat by being electrified, an accommodation chamber in which the heat-generating body is disposed and exposed at the bottom surface and an explosive material accommodated in the accommodation chamber, an opening portion being provided in the accommodation chamber, comprising a step of loading the explosive material from the opening portion of the accommodation chamber by initially loading a first explosive material in a dry state to form a first layer on the heat-generating body and then loading a second explosive material in a wet state to form a second layer on the first layer.  
   
   
       4 . The method for manufacturing an electric igniter according to  claim 3 , wherein the second explosive material comprises a fuel, an oxidizing agent and a binder.
