A vehicle occupant protection apparatus (10) includes an inflator (16) which, when actuated, emits inflation fluid. The apparatus (10) further includes an electrically actuatable igniter (24) which, when actuated, actuates the inflator (16). The igniter (24) includes an ohmic heating element (44) connected between a pair of electrodes (40, 42). An ignition droplet (46) is adhered to the ohmic heating element (44). The ignition droplet (46) is a mixture of pyrotechnic material and a resin binder which is cured by UV irradiation.
