<p>PROBLEM TO BE SOLVED: To provide an injector efficiently heating fuel and atomizing it. SOLUTION: A valve member 20 is formed into a bottomed hollow cylinder. A heat conductive member 30 is formed in an annular shape, and pressure- inserted into the inner wall of a first magnetic cylinder part 13. The heat conductive member 30 envelops the outer circumference of the valve member 20, and the heat conductive member 30 and the valve member 20 form a micro-gap where the valve member 30 can reciprocate inside the heat conductive member 30. A ceramic heater 50 is formed by sintering a heating resistor together with ceramic and molding in a cylinder shape. A case member 60 coverts the ceramic heater 50 so that the ceramic heater 50 is not wetted by water. An inner cylinder 62 of the case member 60 is pressed against the inner wall of the ceramic heater 50 and against the outer wall of the first magnetic cylinder part 13 by the elastic force. Heat of the ceramic heater 50 is transferred to the valve member 20 through the first magnetic cylinder part 13 and the heat conductive member 30, and heats fuel inside the cylinder of the valve member 20.</p> |
