    • The accuracy in controlling the heating temperature of a glow plug and the reliability of the control operation are improved.An electronic control unit 101 is configured such that a standard applied voltage for glow plugs 50-1 to 50-n is set according to the engine speed and the load conditions of the engine. In addition, a correction coefficient set in advance according to the temperature classification of the mounted glow plugs 50-1 to 50-n is readably stored in the electronic control unit 101 as a correction coefficient map. By multiplying the standard applied voltage by a correction coefficient K read from the correction coefficient map and applying a voltage of the multiplication result to the glow plugs 50-1 to 50-n as a driving voltage through the power circuit 102 to perform driving control, stable and reliable heating temperature control can be realized regardless of variations in the heating temperature characteristics.

The pair of element guide portions 33 protrude from an opening end surface on a rear end side of an axial hole 31, store either of widthwise opposite side ends of the sensor element 10 and restrain the sensor element 10 from being inclined. The sensor element 10 is positioned coaxially with the sleeve 30 by the element guide portions 33. Electrode holders 40 in which electrode fitments 60 are held are fitted to the element guide portions 33 so that the electrode fitments 60 are brought into contact with electrode terminal portions 15 and 16 of the sensor element 10.
