IGNITER, METHOD OF PRODUCING THE IGNITER, GAS GENERATION DEVICE FOR AIRBAG, AND GAS GENERATION DEVICE FOR SEATBELT PRETENSIONER

摘要

The invention provides an ignition device which is produced without reducing its productivity, while being compact in size and enabling electric current securely to flow through electric circuits built in the ignition device. The ignition device includes a metal cup and a metal header for holding a plurality of electrode pins respectively insulated and closing the opening of the cup, and further includes, in the cup, ignition charge and an ASIC component. The ASIC component includes an ASIC and a capacitor both mounted on a substrate molded with a resin to form a resin mold, and the resin mold has at its top a heating element connected to the ASIC and further has at its bottom communication electrodes for connecting the ASIC to the electrode pins, so that the ASIC component thus constructed abuts against the header. The electrode pins and the communication electrodes are jointed to each other under pressure.
