A piezoelectric ignition lighter capable of performing an igniting operation by an operation cap (6), comprising a valve mechanism, an injection nozzle (3), and a piezoelectric mechanism (4) installed on the upper part of a lighter main body (1), wherein the operation cap (6) is formed of a polyacet al resin, leaf springs (7, 7) are formed integrally with each other and, when t he lighter is not in operation, a space of approx. 60 to 90% of an operation stroke is formed between the operation cap and the upper end surface (1a) of the lighter main body (1) and, at the beginning of the operation, the operating load is kept at a normal operating level and, after the leaf sprin gs (7, 7) abut on the upper end surface of the lighter main body (1), the operating load is increased by the application of the elastic load of the le af springs (7, 7) to the operation cap, whereby the mis-operation by a child is prevented by increasing the operating load immediately before discharge without unnecessarily increasing an operation load at the beginning of the operation and an excellent controllability for normal users can be maintaine d.
