By using the magnetron sputtering technology, a Ni-Cr metal film bridge which fit for the insensitive electric initiating explosive device (EED)was made and used to ignite the lead styphnate smearing on the bridge center. The safe current, antistatic property, bridge breaking time and function time were tested and was compared with those of the semiconductor bridge and bridge-belt. Results show that when the resistance is (1±0.1)Ω, the Ni-Cr metal film igniting component has a large safety margin, and its function time and bridge breaking time are between those of two under the same condition of heat dissipation. The igniting time of lead styphnate with the Ni-Cr metal film igniting component is less than 1 ms at the excitation current of 5 A.
