In order to solve the problems of long time consumption， high cost and low material utilization in the deposition and forming methods of commonly used thin-film energy conversion component， silver film bridge were prepared by inkjet printing. The morphology and thickness of the silver film bridge were test by scanning electron microscopy （SEM） and atomic mechanics microscopy （AFM）， and the ignition performance was studied. The results show that the thickness of the silver film bridge is 2.1 μm， and the surface roughness is good. The performance test results show that the silver film bridge has two situations of electric heating and electric explosion under different input energy. Under 47 μF pulse discharge， the 50% ignition voltage of the silver film bridge dipped with lead stiphenate （LTNR） is 6.65 V. and the foot-to-foot can withstand 25 kV electrostatic discharge （discharge capacitance is 500 pF， 5 kΩ resistor in series）， which can pass the 1A1W5min test of insensitive electric initiating device.
