Abstract
An igniter circuit is placed inside the sealing container of an associated ignition device to be sealed. The circuit is accommodated behind a partition wall inside the sealing container. The igniter includes a metallic circuit case, a substrate attached to the inner bottom surface of the circuit case, circuit elements attached to the substrate to form an ignition circuit and silicone gel that fills the circuit case. Using the adhesive properties of the silicone gel, a sheet-like protective member is place over the silicone gel to face the partition wall. The protective member may be made, for example, of aramid paper. The protective member is preferably adhesive to silicone gel, can contain gas (air) and is elastic. When the sealing container is filled with insulating resin, a portion of the insulating resin flows to the igniter from an opening of the partition wall. At this point, the protective member protects and separates the silicone gel from the inflowing insulating resin.
