To provide ignition powder reducing the content of a lead compound and ignitable with low energy, and to provide an ignition device using the ignition powder, and a lightweight pyrotechnics firing device having the ignition device and convenient to carry.

(1) The ignition powder contains diazodinitrophenol whose content is 55-75 mass%, lead trinitroresorcinate whose content is 16-26 mass%, and carbonaceous components. (2) The ignition device has a non-bridge type electrode 3 disposed in a frame body 2, abutting on the ignition charge filled in a powder chamber 4, and connected to a piezoelectric element 7. (3) The pyrotechnics firing device comprises a cover formed in an approximately rectangular parallelopiped, and a stored device body comprising the ignition device, a magazine 9 filled with lighting powder 8, and a pyrotechnics firing hole for firing the light powder as the pyrotechnics.
