Abstract
In a fuel injector, a valve member in a hollow cylindrical shape having a bottom is enclosed and supported in a magnetic cylinder defining a fuel passage to reciprocate in an axial direction. At least two of the ceramic heaters having an arc shape in cross section are arranged on the outer periphery of the magnetic cylinder in a circumferential direction to be a cylindrical shape. The ceramic heaters are pressed toward the outer periphery of the magnetic cylinder by a heater holder with a small resiliency. The ceramic heaters are tightly fitted on the outer peripheral surface of the magnetic cylinder without being damaged. Therefore, heat of the ceramic heaters is conducted to the magnetic cylinder and fuel in the magnetic cylinder is effectively heated.
