Summary:PROBLEM TO BE SOLVED: To omit a grounding-back line to a controller that has been necessary when an ignition plug is used for measuring an ion current. SOLUTION: An ignition plug is provided with a heating rod 1 having an inside heating coil and one or more coil when required, and the heating rod 1 is insulated from an ignition plug main body and provided with a plug or screw terminal for power source voltage. The terminal 4 is provided with a chip having an electronic part 6, preferably a connection terminal 7 to a power source voltage, a connection terminal 8 to an ignition pipe and a grounding terminal 9 to the main body 3. The electronic part 6 is designed as a control element for switching the ignition plug to a heating function and a sensor function for measuring ion current in a combustion space zone in the neighborhood of the heating rod.
