打火机，是生活用品，自生火焰的工具，它取代了从前的火柴、打火石/火镰、钻木取火、火种盒。

打火机的由来有两种说法：

1924年打火机开始大量生产。打火机的发展历史中，使用过的引火材料包括苯、煤油和现在应用最普遍的丁烷。点火方式方面，二战后日本人用压电陶瓷电子生火替代了人造打火石，为现在打火机最普的点火方式。一次性打火机，或称抛弃式、简易型打火机，由**人发明并申请专利，后高价让与日商东海千辉。

A lighter is a portable device used to create a flame, and to ignite a variety of combustible materials, such as a cigar, gas stove, fireworks, candle, or cigarette. It consists of metal or plastic container filled with a flammable fluid or pressurized liquid gas, a means of ignition to produce the flame, and some provision for extinguishing the flame. Alternatively, a lighter can be powered by electricity, using an electric arc or heating element to ignite the target.
