In a plug that ignites fuel for an internal combustion engine by discharging between a center electrode and a ground electrode, the center electrode is directed toward the center axis from the prefecture side to which high voltage is supplied. What is claimed is: 1. A spark plug with a built-in pressure sensor, characterized in that the spark plug is divided into a discharging section and a distal section that discharges electricity, and a pressure sensor is provided between the distal section and the distal section. 2. The spark plug with a built-in pressure sensor according to claim 1, wherein the pressure sensor receives preload from the center electrode on the prefecture side and the center electrode on the front side. 3. The pressure sensor built-in spark plug according to claim 1 or 2, wherein the center electrode also serves as one of the lead wires of the pressure sensor. 4. The spark plug with a built-in pressure sensor according to any one of claims 1 to 3, wherein the center electrode on the side ahead of the pressure sensor has a high natural frequency. 5. The pressure sensor built-in spark plug according to claim 4, wherein the pressure sensor is provided near the tip of the center electrode. 6. The spark plug with a built-in pressure sensor according to claim 4 or 5, wherein the center electrode on the front side of the pressure sensor is made of a material with a lower mass than the center electrode on the prefecture side. 7. The spark plug with a built-in pressure sensor according to any one of claims 1 to 6, wherein the discharging portion at the tip of the center electrode ahead of the pressure sensor is made of platinum or conductive ceramic. 8 Utility model registration claims 1 to 7 in which the portion of the center electrode on the side beyond the pressure sensor that is exposed in the combustion chamber of the internal combustion engine bulges out in a direction substantially perpendicular to the center electrode axis. A spark plug with a built-in pressure sensor according to any of the above.
