The invention relates to a lighter, in particular to a high-frequency electric arc lighter. The high-frequency electric arc lighter comprises an outer shell and an electronic firing circuit arranged in the outer shell. The electronic firing circuit comprises a direct current power source, a high-frequency arc ignition circuit, a pair of spray points and a contactless electronic switch. According to the high-frequency electric arc lighter, a power field-effect transistor of a double-MOS transistor which is low in internal resistance, low in drive voltage and driven by low voltage is adopted to form the contactless electronic switch to serve as a power source main switch, and is suitable for the electric arc lighter with the lithium battery as the power source, and no mechanical contact exists, so that work is more stable, and the service life is longer; a transient high-voltage absorption circuit and a delayed discharging circuit are arranged, so that unexpected overvoltage in the debugging process and in the use process is avoided; the high-voltage arc ignition circuit uses detachable metal tapered needles, so that the high-frequency electric arc lighter is precise to position, convenient to replace and low in noise, and arc ignition is achieved easily; the mechanical switch is replaced by the touch switch, so that the high-frequency electric arc lighter is beautiful and elegant in appearance and free of abrasion.
