<p>The object is to prevent damage to and overheating of an electric wire for electric discharge/ignition of a burner, thereby increasing its life, without increase in cost. The burner includes a housing 1, an intake pipe 3 and a burner head 4. Gas in the housing 1 is supplied to the burner head 4 through the intake pipe 3. An electric wire 8 extends through the intake pipe 3 which connects a piezoelectric element 7 to a core wire 10 from which electric discharge is generated near burner ports 9 of the burner head 4 by the piezoelectric element 7. Since the wire 8 is not exposed to outside the intake pipe 3, the wire 8 is never caught and damaged by an external object. Since air-gas mixture which is kept at around the room temperature is flowing through the intake pipe 3, the wire 8 is less likely overheat during use of the burner. Thus, it is not necessary to provide the wire 8 with a shield plate for protecting the wire 8. This simplifies the manufacturing steps and thus reduces the manufacturing cost.</p> |
