Abstract
Forming a filter for a gas lighter using a sintered porous ceramic, and adjusting the flow rate of gas through gas passages formed by interparticle pores of ceramic. There will be no change in the flame length even in the use of the gas lighter over a long period, thereby enhancing the safety of the gas lighter.
