The present invention intends to provides a piezoelectric ignition lighter capable of avoiding misuse by children but maintaining excellent operability for normal users without unreasonably increasing actuation load at the initial ignition operation. For this end, the piezoelectric ignition lighter has a valve mechanism, a nozzle 3 and a piezoelectric mechanism 4 at the top of a lighter body 1 and ignites by actuation of an actuation cap 6 integrally molded of polyacetal resin with torsion plates 7,7. The torsion plates 7,7 are separated from the upper end surface 1a of the lighter body 1 by a gap equal to about 60%~90% of the actuation stroke in the non-actuated condition to provide a normal (light) actuation load at the initial actuation stage. After engagement of the torsion plates 7,7 with the upper end surface of the lighter body 1, resilient load of the torsion plates is added to normal load, thereby increasing the actuation load.
