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.

Claims

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.
