PROBLEM TO BE SOLVED: To prevent a deposit from accumulating on an wall surface of an injection hole 13, in an injector for injecting and supplying fuel. SOLUTION: An injector includes an exothermic body 41 disposed facing the inside of an injection hole 13 for heating the wall surface of the injection hole 13. Thereby the deposit adhered to the wall surface of the injection hole 13 can be burnt out by being heated by the exothermic body 41. Thus, the deposit can be prevented from accumulating on the wall surface of the injection hole 13. COPYRIGHT: (C)2009,JPO&INPIT
